Very cool! Clearly I had a long way to go with mine to get it under the IOCCC requirements :) Though my goal was specifically Pokémon... curious how much more you would need to be able to run that.

rgbds-live is more-or-less this same idea, with an embedded version of RGBDS: https://gbdev.io/rgbds-live/

Glad they've helped! There are plenty of better emulators, but I'm pretty proud of binjgb for being small, pretty fast, and pretty accurate.

heh, good point! Most of the older ones are using GameBoy-Online[0] instead, since that was the GB Studio default for a while. But I think everything since GBStudio 3 should be binjgb. [0] https://github.com/taisel/Game

This is using my gameboy emulator, binjgb[0], on the website! (well one of my gameboy emulators, heh [1][2]) It's been used as the emulator for GB Studio for a little while now, but I don't know how often people embed it in their

Thanks! I don't work much on WebAssembly anymore, but I'm super excited to see all the progress being made.

That's true, I should have mentioned that I use this extension. It is supported by clang as well, however.

This was brought up for the last one of these I made, but the code here is c++ so wouldn't be allowed. I don't use a lot of c++ features, but it might be hard to keep the code size small without them.

Hi all, author here! Happy to answer any questions y'all have

I didn't handle audio for this emulator. But you can see how I handle resampling in my more fully-featured NES emulator here: https://github.com/binji/binjnes/blob/ca6977469168069a165176... I'm not

I think so, when I was doing the write-up I noticed a few things I could have improved (and a few bugs!)

I kind of dreaded writing that one, to be honest! I didn't quite cover all the details but I hope it made a little more sense. :)

Yes, you can find all the meeting notes here: https://github.com/webassembly/meetings However there were a lot of discussions that were not in those meetings and were in smaller groups or held in GitHub issues or PRs.

Yep, I made a mistake it's actually 68.

Ha, I guess we'll see when I go for my next gig :-)

I'm probably the wrong person to ask, to be honest. I was around for a lot of the design of Wasm, but wasn't really involved at that level. That said, in my opinion the ideal set of opcodes really depends on your goal. There were

Not sure, I think it should! Would be really cool if someone tried it out. I'm a little worried I didn't implement some necessary instructions/hardware features so the game isn't actually winnable :-}

Oops you're right, I should have mentioned that. Red works too, I just didn't want to write Blue/Red everwhere :)

JVM is a great choice! You might also want to check out WebAssembly too (full disclosure: I used to work on wasm). There aren't too many opcodes, and a lot of them are relatively simple math operations. Once you get it working, you cou

I got kinda dragged about this on reddit/twitter. Afterwards I posted on r/tinycode with the size in bytes: https://www.reddit.com/r/tinycode/comments/nn5djb/pokegb_a_g...

It really is one of the best things about emulation development. It's surprising how quickly you go from "nothing works" to "I'm playing Super Mario Bros!"

Hi all, I'm the author of this post! Happy to answer any questions. :-)

Very nice write-up, thanks! BTW, I also ran into issues with ScriptProcessorNode when generating audio, and ended up using `createBufferSource` with a scheduled playback time. I wrote a little about it here: https://binji.github.

You may want to take a look at the formal spec here as well: https://webassembly.github.io/spec/ There's still some work to be done, but it is quite far along already.

As long as we're linking personal GB emulators... :-) Here's mine, written as one file of less than 5000 lines of C: https://github.com/binji/binjgb . It's very accurate, based on few of the most commonly

That appears to use https://github.com/WebAssembly/polyfill-prototype-1 , which does not match the current binary format at all. The current way to do the equivalent would be to use Binaryen's asm2wasm tool. https

TeaVM[1] has an experimental WebAssembly backend that does something like this. Here's the recent Reddit thread[2]. [1] http://teavm.org/ [2] https://www.reddit.com/r/programming/comments&#x2F
