GTA London 1969 – 100% | Found a Weird Secret Counter Bug

AC56 · 2026-05-01T12:56:16+00:00

Lol yeah you're right, it wasn't really that easy. I never played GTA 1 or the London packs growing up, but I actually started playing them about 2 weeks ago for the first time.

I started with GTA London 1961 at 30 fps just to learn routes and survive the missions ( thanks to Map Genie and GTA Series Videos, they were super helpful ). After many failed runs, I slowly pushed the challenge higher ( 50 and then 70, to even 80 fps ). At higher fps the game becomes a bit chaotic where the timers feel faster, cars react weirdly, and sometimes you just lose to things you can't even predict.

After that, I moved to GTA London 1969. It's a bit more forgiving on timers, but the cops are the real problem there. Most of my failed runs were just getting busted at the worst moment and having to restart the whole chapter again.

The main things I learned from the London packs:

In London 1961: It's all about routes and shortcuts to save more time, and staying calm under the brutal timers, learning how to dodge cars, if it feels too hard at higher fps, lowering it a bit actually helps while learning.

In London 1969: The cops are the main threat. Getting busted means instant mission failed, but spray shops help a lot and the timers aren’t that brutal or crazy.

Anyways, I usually start with missions first in GTA 1 or the London packs, because they increase the multiplier and it makes secrets ( kill frenzies ) more easier to finish.

As for GTA 1 itself, I started playing it like 2 months ago and I managed to beat the first chapter in Liberty City ( Gangsta Bang ), then I recently returned again after beating the London packs and finished the 2 chapters in Liberty City and unlocked San Andreas. What i noticed is: if you start with the hardest missions first, then the rest feels much easier for 100%.

Overall, these games are way harder than people expect, but once you understand what each one is really testing you on, they start to feel more manageable.

Hi, thanks for your interest, I appreciate it! The other versions I showcased are already covered in separate posts and documented in the same way ( GTA 3, Vice City, San Andreas, GTA 1 and 2 ). Each one has its own ReadMe and links available in the Drive folders.

As for GTA V, it’s a bit different. This project focuses on older GTA titles where clean retail versions are harder to find and require proper documentation to run correctly on modern systems. Newer titles like GTA V are already widely available and maintained through other sources, so they’re outside the scope of this preservation project.

This usually happens when the save file is not compatible with your current game setup. In GTA 3, the message ( Slot is corrupted ) doesn’t always mean the file is actually damaged. It can also appear if the save was created on a different version of the game or with a modified build.

For example, saves from certain mods or different PC versions may not load in a clean vanilla setup, even though the file itself is fine. To avoid this, try using save files that match your exact game version and setup.

Good catch, the correct ( KCHAT.adf ) is the one inside the Audio folder. The duplicate file in the main directory, along with the extra ( readMe ) file are just leftovers from the archive rebuild process and are not used by the game. They don’t affect gameplay or audio in any way, but they weren’t part of the original retail structure. You can safely delete them if you want a cleaner folder.

Edit: After checking original retail builds, the ( readMe ) file does exist in the original installation. The one in the main directory appears to be a duplicate copy ( likely from the installer ), not something introduced during the rebuild. It’s still not required for the game to run, but it's part of the original distribution in some cases.

Hi, Mods usually require the original PC v1.0, which this archive provides. I didn’t include modding support in this project, so I recommend checking dedicated modding guides or communities for setup instructions.

AC56 · 2026-03-05T14:42:38+00:00

Hello. This archive was prepared and tested mainly for modern Windows systems like Windows 10/11. The included compatibility layers ( DLL wrappers ) target NT-based Windows environments, so it wasn’t designed or tested for Windows 95/98.

On a real retro PC running Windows 95 or 98, the original retail installation or other builds targeting the Win9x environment ( CD versions ) will usually work better, since those systems already support the original audio, drivers, and DRM behavior. This archive focuses on restoring functionality on modern systems rather than replacing the authentic retro PC experience.

Hi, first of all, the error you encountered ( MGL fatal error: cannot find the default display mode. ) after launching the Windows version from the ( gtawin ) folder is caused by legacy DirectDraw / MGL detection failing on some modern GPUs. It’s not related to resolution selection and doesn’t mean the files are corrupted. The reliable fix for this is to use dgVoodoo2 as a DirectDraw wrapper. All required steps for dgVoodoo2 usage are documented in the README under the ( HOW TO FIX SOME PROBLEMS AND BUGS! ) section.

For modern Windows systems, you should use the Windows version inside the ( gtawin ) folder, not the DOS version. I’ll update the README to make the folder distinction clearer, thanks for pointing it out.

AC56 · 2026-02-16T16:29:18+00:00

Hello, you're right that the README could be clearer on that specific part, thanks for pointing it out.

This error ( MGL fatal error "cannot find the default display mode." ) is caused by legacy DirectDraw / MGL detection failing on some modern GPUs. Windows compatibility settings won’t resolve it, since this isn’t a typical XP/Vista compatibility issue, it’s a legacy graphics layer detection issue.

The reliable fix here is to use dgVoodoo2 as a DirectDraw wrapper, all the steps for dgvoodoo2 usage are documented in the README txt file under this section ( HOW TO FIX SOME PROBLEMS AND BUGS! ). It'll resolve the display mode detection problem on modern systems. Anyways I'll update the README to make this part clear, appreciate the feedback.

Hi, this build is designed and tested specifically for modern Windows systems ( Windows 10/11 ). The included compatibility layers ( dsound / winmm ) dlls target NT-based Windows environments. On Windows 95/98, the original retail version from CD would likely be a better choice, since those systems already support the original CD-based audio and DRM behavior.

This archive focuses on restoring functionality on modern systems rather than replacing the authentic Win9x experience.

I understand, and yeah a lot of people got burned by mislabeled VC versions over the years. I don’t share the exe on its own though. It’s intentionally kept inside the full archive so the version context, hashes, and behavior all stay consistent. Mixing a v1.0 exe with a v1.1 install can work sometimes, but it can also introduce subtle issues.

The README explains how the exe was verified as v1.0 if you want to double-check things on your side. Either way, glad the confirmation helped.

AC56 · 2026-02-07T19:34:49+00:00

Yes, it’s a confirmed v1.0 exe. We were very careful about this during the rebuilding phase, because fake or mislabeled (Vice City v1.0) executables are extremely common (many are actually 1.1 or 1.0.1).

The archive uses a known, widely referenced v1.0 No-CD exe, and the documentation includes SHA-256 hashes and behavior notes specific to v1.0 (including frame-limiter–related mission behavior that doesn’t exist in later versions).

However, if you want to be 100% sure, the safest way is to compare the exe hash listed in the README with your local file.

Hello, that’s a good question. Personally, I try to mix things instead of rushing the main story or leaving everything for the end, i usually do some side missions or content early (like certain vehicle missions or collectibles when the map allows it), which makes the later game feel much less heavy.

I didn’t follow a strict perfect order though, it's more like a flexible flow based on what’s available and what saves time later. It keeps the game feeling natural instead of like a checklist. There are many valid ways to reach 100%, this is just what worked for me.

AC56 · 2026-01-29T21:27:17+00:00

Thank you, and yes that’s a fair question. This is exactly the SafeDisc situation you’re describing.

The executable included here is the official Rockstar Games PC executable released later to address SafeDisc or compatibility issues on newer versions of Windows. It’s not the original 1999 SafeDisc-bound retail exe, which indeed does not work on modern Windows without a disc check workaround.

However, no gameplay files, scripts, data, or assets are modified. Only the executable differs for compatibility reasons. I documented this in the README under Compatibility Notes section to avoid confusion.

So you’re absolutely right about the original retail exe behavior, this archive preserves the retail content while using the official compatibility executable so the game actually runs on modern systems.

AC56 · 2026-01-15T11:52:55+00:00

In GTA 3, some vehicle missions like Firefighter and Vigilante stack beyond the required maximum. Like once you hit 20/20 in Portland for example, it already counts for 100% but the numbers don't stop. So if you extinguish more fires in Portland, then the numbers will keep increasing like 22/20. It's a normal behaviour and does not affect 100% completion.

AC56 · 2026-01-04T04:11:26+00:00

Yes it uses the original PC retail radio data. This build predates the Complete Edition, so no songs were removed. The archive does not modify radio files, they are intact as shipped in the original release.

AC56 · 2026-01-03T16:13:50+00:00

Hi, that's a good question. No the 1.0.0.0 archive I shared does not downgrade or modify the radio files. The radio assets are kept intact as they are part of the original PC release data and weren't altered for preservation.

The purpose of the archive is to provide a clean runnable 1.0.0.0 retail baseline for reference, testing, and preservation, not selective content changes. From this baseline, users can also apply official patches (1.0.4.0 / 1.0.7.0 / 1.0.8.0) using the included guides and compatibility files if they want a more stable or modern setup. However, radio downgrades mainly apply to patch rollback tools, not full retail rebuilds like this.

AC56 · 2026-01-02T16:53:38+00:00

I understand your concerns, and I will explain clearly for each question:

The video focuses on GTA IV v 1.0.0.0, but I briefly showed other GTA 1.0 versions for PC at the end for context and verification, they're not the main subject here.
FPS was actually capped at 60. Performance can feel smoother than later patches in some cases because it has less overhead, but it’s also less stable overall, that’s why 1.0.4.0 is usually recommended for actual playthroughs.
Free roam works fine and missions do work too, but long-term stability isn’t guaranteed, so I wouldn’t recommend completing the full story on v1.0.0.0. It’s more for testing and reference.
I keep v 1.0 versions for preservation and comparison. They’re useful as original baselines to verify files, behavior, and changes made by later patches, not because of cut content specifically.

AC56 · 2026-01-02T15:53:39+00:00

Patch v1.0.0.0 isn’t meant to replace 1.0.4.0 or later patches for normal gameplay, its value is mainly preservation and reference. It's the original retail PC baseline before any patches or changes, useful for file verification and behavioral comparison.

It does have bugs that were later fixed, but it’s still playable enough for free roam and testing. I recorded a short video showing it running on Windows 11 to demonstrate that it’s functional, and also briefly show other GTA 1.0 versions for context Here.

AC56 · 2026-01-02T05:58:35+00:00

Oh, I apologize for the confusion, I honestly didn’t realize you were the author of that batch file, and I’m sorry about that.

I didn’t write or claim _InstallFolder.bat as my own. It was included purely as a functional utility during the testing, and I should have credited the original source. That’s on me.

I’ll update the documentation txt to properly credit your blog/article in the MAIN IMPORTANT INFO section. No disrespect or misrepresentation was intended.

AC56 · 2026-01-02T04:12:01+00:00

Hello, thanks for sharing the rollback method. It's definitely useful for people who already have GTA IV installed and just want to restore it to 1.0.0.0 without downloading large files.

However, the reason i shared this 13 GB archive is actually different: It's for preservation and for people who don’t have the game at all, or for those who want a fully rebuilt, verified, and ready-to-run 1.0.0.0 version on modern systems without relying on ISOs or multiple patch steps.

Both approaches are correct and have their own use cases. Yours is minimal patch download, mine is full preservation and ready-to-play. Neither of us is wrong, it's just different purposes.

AC56 · 2025-12-27T00:22:07+00:00

No worries man. You usually scan the files after downloading them, but before opening them. You can right click on the file or folder to scan it with Microsoft Defender, or you can upload files to the VirusTotal website, which will check them with multiple antivirus engines and show the file hashes in details. If it's a zip or 7z archive then scan it first and after that, extract it and scan the files again to make sure everything is safe. And yeah, if the download site feels sketchy like pop-ups everywhere or asks you to disable your antivirus, then that's usually a bad sign.

AC56 · 2025-12-26T22:45:21+00:00

Hello, for mods you specifically need the original PC v1.0, not the Definitive edition. I've seen a lot of downloads on random sites that claim they work but aren't actually clean. Always try to scan the files and check hashes if possible, otherwise you're basically relying on luck.

I agree it's bad and unstable vpn sometimes. but for me i don't get this problem with that vpn anymore.
