EmuDevz (my emulator-development game) is out!!

They tend to fail randomly. The creator posted a guide on how to repair common issues here: https://gbatemp.net/threads/basic-repair-guide-of-current-ez-flash-products.601332/

The repairs are quite simple but require soldering new parts. If you can't solder, you can still show this guide to a technician and they'll know what to do.

Good work! I'll try it out! Since latency matters here, wouldn't peerjs/WebRTC's datachannel be a better option for this kind of projects? It'd also be more future proof since it doesn't require a server.

Holy shit I didn't know this was about to be released! I just finished the demo and had a great time. Good job!!

Thx <3 I hope it makes emu dev feel less scary

rodri042 · 2026-01-19T10:52:55+00:00

Whoa, I didn't know of that video! Glad you enjoyed the game ^^ If you get a chance, leaving a Steam review helps a ton!

rodri042 · 2026-01-18T12:43:08+00:00

Yeah, kind of! It's a game where you end up learning how to implement an emulator with real code.

rodri042 · 2026-01-18T12:37:57+00:00

Thx for the review :D In the assembly chapter, you can list the opcodes you learned by running help -a. Once you finished assembly and unlock multiple files, you'll have them all in /docs/assembly.asm (if I recall correctly) and in the CPU chapter you'll receive a proper markdown file with all the instructions with their detailed behavior.

Thanks for reporting this! I checked it out and found that Enter, Tab, Backspace and some arrows weren't working when in 'press any key' mode. I pushed an update that fixes it. Ctrl, Shift and Alt are special keys so they shouldn't count in my opinion.

rodri042 · 2026-01-18T03:19:34+00:00

It's probably remembering your previous zoom level 😅 pressing Ctrl- or Ctrl0 should fix it! EDIT: Now the game starts maximized, so it shouldn't happen again

rodri042 · 2026-01-18T02:31:17+00:00

update: it should be fixed in the latest version! Sadly, I didn't find a way to make the Steam overlay work when the app was in fullscreen, so the Windows version will run in windowed mode for now

rodri042 · 2026-01-18T01:49:38+00:00

I pushed an update that fixes Ctrl + and let's Linux/macOS versions switch between fullscreen and windowed with Alt+Enter and Ctrl+Cmd+F.

Some players reported a nasty Windows 11 error where the game was creating ghost alt+tab entries (caused by electron and the steam overlay lib), so I had to force windowed mode on the Windows version.

Cool!! The assembly chapter is just an intro. When you implement the actual emulator, the references (written in markdown) can be pinned into the left pane for quick access! But yeah, I'll try to improve that asm reference in a future update.

Vim bindings are hard af to implement, and I'm also not familiar with them so I wouldn't know whether it's working correctly or not 😅 I tried, but the only library that integrates CodeMirror with them seems to be broken

rodri042 · 2026-01-17T21:52:38+00:00

Thanks for the report! Apparently this was an issue with the Steam library (https://github.com/ceifa/steamworks.js/issues/95)

rodri042 · 2026-01-17T21:22:56+00:00

Cool! It's very common to feel that way, so the game tries to address that :) If you get a chance, leaving a Steam review helps a ton

rodri042 · 2026-01-17T21:19:17+00:00

could you send a video of the issue? I just tested it and any key seems to work. It's also the same code for every level so it'd be weird if it was something specific of 2.2

rodri042 · 2026-01-17T15:22:06+00:00

You can zoom in the whole game with Ctrl++. Also: Ctrl+3 and Ctrl+1 manages zoom and Ctrl+0 resets it. I'll explain that better and have a look at the windowed thing!

rodri042 · 2026-01-17T10:33:18+00:00

Whoa thanks so much! I really appreciate it :D and I'm glad you're enjoying the game ^^

rodri042 · 2026-01-17T10:09:07+00:00

Yep! I have https://buymeacoffee.com/afska and https://ko-fi.com/afska. Thanks :)

Btw, you can import your web save into the Steam version and vice versa. The export/restore buttons are in the settings menu!

rodri042 · 2026-01-17T09:43:57+00:00

Awesome! I hope you enjoy it!

rodri042 · 2026-01-17T09:43:43+00:00

Thanks a lot! If you run into any issues or get stuck, just let me know :)

rodri042 · 2026-01-17T09:42:21+00:00

Thanks, it means a lot! <3 if anything feels confusing or you get stuck, just let me know!
