TI-Nspire GB Emulator
« on: November 30, 2009, 02:37:13 pm »
Since Goplat released the beta of his TI-Nspire emulator (as featured on ticalc), I decided I could start writing some code to eventually run on the TI-Nspire once it gets cracked. So, I've started a Game Boy emulator (again) :)

Not much runs at the moment - Link's Awakening in particular has some major issues (probably related to some mistake I made in the cpu emulation). Only the background tilemap is supported so far - no sprites or window.


Probably the next thing to do would be to get sprites working.

That is so awesome, I am curious if it will be easy to modify the code so it runs on future TI-Nspire OSes instead of just on emulator by replacing the Nspire emu boot code?

I can't wait to see more progress on this and possibly (calcalture animated) screenshots

Looks nice. Will it be the same as on the 83/84s or will there be more features?

Hopefully it won't need as many "features" (such as zooming and sprite tracking) since it all fits in the screen. But, it will hopefully have better compatibility and full speed. Also, it could eventually support Game Boy Color, minus the color.

Edit: Oh, and I just realized that I have light-gray and dark-gray mixed up in that screenshot. I have that fixed now :)

*Builderboy explodes again*

That is constructed from pure awesomness!!!  How is it coding for the nSpire?  Like, its still with asm, but how do you compile to hex code if it isn't a z80 chip?  Or is it not asm, and some kind of C compiler?

There are C compilers for ARM, but I haven't really bothered messing with them. This was coded in ARM assembly language (which does go to hex code - each opcode happens to be four bytes large). I'm still a little new to this language though.

Added sprites. It's looking quite nice :)

Still no window support, which is why the bottom of the screen doesn't have the status bar.

Edit:
CalcCapture doesn't like me. Or, at least, it doesn't like that the graphics window can't be in focus for me to press any keys. So it doesn't look like we'll be getting any gameplay animations. On the other hand, I recorded a bit of the Kirby title screen :)

Got Link's Awakening working after fixing 20 or so broken opcodes (some of these were unrelated to the problem, but hey, it all counts right?)

Nice :D

Now let's hope TI won't shit on us with a new TI-Nspire hardware like they did with the TI-84+ in mid 2007

Obligatory screenshot:


Note that there are some graphical glitches in the second half. These were in TI-Boy too. But hopefully I'll get them fixed this time around! :)
