TI-Boy SE

Indeed, I have been making a Game Boy emulator for the TI-83+SE, TI-84+, and TI-84+SE.

It currently supports two zoom levels, and another is planned as well. When zoomed in, you can configure the camera to follow any sprite (most often you will want this to be your character).
It also supports two out of the four Game Boy sound channels, so you can plug in your headphones and enjoy. :D
Only two games are known to work at the moment: Tetris and Link's Awakening. Tetris runs at almost full speed, while Link's Awakening is more at about half speed (but still very playable!)

I uploaded a Youtube video of Link's Awakening for your enjoyment. Beware, the video and sound aren't fully synchronized.

Next on the list for compatibility is the special rendering techniques which are employed by many games.

Now everyone who said only 68k calcs could achieve such things as GB emulators have been proven wrong. Sure, there's no grayscale at 100% screen zoom but this is still insane so far and I am amazed at how fast it runs given the signifiantly larger GB screen and the fact the 83+ doesn't support a lot of stuff the GB does, even if the processors are similar.

Nice work Calc84maniac and I am surprised how well it emulate games so far :)

I wonder if it will emulate homebrew games and rom hacks too?

wow... that is really amazing.  So by emulate, you mean run directly from the original game files?

Yep... it interprets every opcode of the Game Boy's processor. Kind of like parsing TI-Basic, but simpler. :P

Glad to see a topic for this now. Does sound affect the speed at all?

Not noticeably, from what I can tell. It is interrupt-based, so it tries to only interrupt the code when it needs to.

If you are able to phrase the code of the GB files, could you make a app that would phrase TI-Basic files more intelligently?

now that you mention it, that could be a nice idea =)

If it still used the BASIC editor on calc, it would require a whole load of hooks, though

Like I said, Game Boy machine code is a lot simpler than TI-Basic. The reason it's so easy to parse is that assembly opcodes don't do very much at all. :P
