Nice job man! Can we seem some screenies soon?

Too bad I don't have any GB model at all (GB, GB Color, GBA, SP, DS), otherwise I would have helped in testing it.

But I still want to see screenies!

And what are you going to do about the 50 buttons?

Right now, it's in the extremely early stages. It's in the stage of "Let's rip apart this Sega Master System emulator and remove everything SMS specific" stage.

I thought you would have used the goomba code. but I guess a real z80 makes more sense.

Would the SMS core be portable to the DS?

(for the SMS) Same assembly language. The Z80 core ports with zero effort. The graphics code just needs some memory moved around. The sound code might be tricky, needs to run on the DS's second processor in order to play anything, even though the sound is already completely software-synthesized.
Finally, need to find a much less lazy programmer to actually convert it.

You should contact the guy who made a DS version of the TI-85. There might be some things already done you could use from that.

Cool project (especially with the SMS angle).

Yeah, but doing it for the GBA is going to be difficult. The DS has the touch screen where all the buttons are emulated on the 85, but I don't think it could be done on the GBA. If so, it's going to take too much effort and be impractical.

Not really, just use the d-pad for a mouse.

Just needs a little more debugging... Hopefully it will say Mem Cleared soon.

Edit: Figured out what's up now... Calculator is Off. Need to emulate the ON button now.

Edit: Obviously an ON button's not enough, need to fix more bugs.

a mouse? What, do you want to select buttons on screen? Then you'd only be able to see the buttons or the screen at one time, not both. It would be slow to use. Maybe, if you intend to use it for games, you could let the user customize what buttons would correspond to what calculator buttons when the emulator first starts. Like, map the apps key, 2nd, alpha, mode, clear, on, and arrow keys to dpad.(keys used for mario) Then you could play some games, at least.

The way I plan on doing keyboard input is that you will select between Onscreen keyboard mode, and fullscreen mode, with the ability to customize the keys for fullscreen mode.

that sounds like the best solution for a GBA emulator.
