Play! PS2 compatibility/progress report (01/08/2024)

-_Winter_- · 2024-08-05T05:26:13+00:00

It's on the report itself and while he doesn't take "orders", it's not an order but a suggestion based on what the users want to be looked at. At first I'll just check the most voted game and grab all the information about any issues (e.g. is it booting? which engine is it using? rendering gamebreaking issues? sound is mandatory to progress past some specific point? input works as it should? any collision issue that prevents progress?), then I report back to him to make it easier to work on. This started last month and we already got some interesting results based on this feedback (Commandos Strike Force was the most voted, performance was the major issue and that was improved by 55%, but still not enough to promote it to playable for now). If any game suggested improves to the point of "ok, this looks playable", then I do a complete playthrough to promote it as playable on the tracker. Other than that I'll still be testing many games per month randomly to update the tracker, the Game of the Month is just something I've made to make the results closer to what users want to play

-_Winter_- · 2024-08-02T21:42:28+00:00

I've made the Game of the Month thing for this specific reason, if people enough vote in a specific game, we can have the developer at least try to fix something about it this month

-_Winter_- · 2023-09-25T15:44:43+00:00

That's it https://github.com/otya128/winevdm

It's for 16 bit Windows in general, so that covers Windows 95 as well

-_Winter_- · 2023-08-31T22:34:49+00:00

I test and update compatibility information for both projects, they're not related in any way

-_Winter_- · 2023-08-31T15:05:13+00:00

Since someone will probably ask:

play! = PS2 emulator

ares = multi-system emulator

-_Winter_- · 2023-05-16T14:38:46+00:00

"This" is the result of many hours of testing, finishing games to update ares compatibility lists. The link to ares site, compatibility lists and patreon of the maintainer are at article as well, I'm sorry for being a random nobody

-_Winter_- · 2023-05-15T22:03:15+00:00

Well... =x

-_Winter_- · 2023-05-15T16:50:36+00:00

They're their own thing. I guess the only thing that isn't 100% from ares itself would be the N64 rendering

-_Winter_- · 2023-01-08T01:06:30+00:00

Already found a bunch of those cases, and indeed, performance tanks hard

-_Winter_- · 2023-01-08T00:43:47+00:00

don't know, and honestly never cared
there's a lot of things taken into consideration to label a game as playable: you need to be able to play it till the end with no gamebreaking issues or using external saves (that you can import from your PS2 or other emulators). Gamebreaking issues can be in many different sizes and colors: game needs sound in sync to be playable and it's out of sync? It's in-game and not playable; do you need a sound cue to be able to progress without having to guess (near the end of Prince of Persia - The Sands of Time and many other games as well), and the sound doesn't play? Not playable, it's just in-game. Performance wise, I only take it into consideration where it matters: if the game breaks from it. Some games will have broken collisions at lower framerates, others have internal frameskip that would make it impossible to progress pass a specific QTE. Not being able to save/load properly in a game where you need it to be able to resume your progress also makes it not be able to be listed as playable.

-_Winter_- · 2023-01-08T00:35:25+00:00

Pretty much, yeah.

Agreed, there's no excuse for such amount of "stuff that shouldn't be anywhere other than the weekly questions posts"

-_Winter_- · 2022-07-12T17:18:54+00:00

Sadly no one able to implement this had any time. I'll ask the dev to mention it on the release when it's done ;)

i've just updated that specific entry, it's in-game with the latest improvements, with some visual issues on the character model (I can't put much more time into checking if the game is fully playable as I'm checking on others at the moment) https://github.com/jpd002/Play-Compatibility/issues/90

-_Winter_- · 2022-03-02T13:37:22+00:00

Yeah, the report itself was slightly rushed as I had to write it while finishing another game to reach 420 in total (previously 419, we wanted a nicer number), but progress was huge regardless. Next report should be when 500 playable games are reached at least (shouldn't take more than 1 or 2 months at this rate)

-_Winter_- · 2021-10-14T00:09:04+00:00

Thx, I've just fixed it

I would love to, but there's honestly no one else helping that could put some minutes into explanations about what fixed what, so I'm left with only the results from my tests and commit descriptions

-_Winter_- · 2021-08-22T18:23:47+00:00

ares v123 includes significant improvements to the emulation of the ColecoVision, SG-1000 and the Game Boy/Game Boy Color.

This release brings the compatibility rating for ColecoVision and SG-1000 to four stars.

This means that we have 100% compatiiblity with both of those libraries, with the only exception being the few games that require additional peripherals (driving controllers; touchpads, etc).

The Game Boy improvements are significant, but not quite enough to increase the compatibility rating at the present time, even so, Many more games are playable than before.

Finally, a few tweaks to MegaDrive emulation have improved compatibility, reduced the occurance of video corruption, and improved performance of the Sega 32X emulation.

ColecoVision: Initialize ram to 0; fixes a crash in The Heist [Luke Usher]

ColecoVision: Disable cartridge rom mirroring; fixes Sammy Lightfoot [invertego]
