DSemu-0.4.2

Firstly a major bug : The top screen is almost ALWAYS BLACK. This applies to EVERY demo, except space invaders and calculator.

Test Results - changes from 0.4.1 will have (*) after them.

Very interesting post, please continous testing nds emu.

It's DSemu, not NDS emu. NDS Emu is the name of a rip off emu.

Yes, I very cleverly broke the sub screen in my last update, sorry about that!

The fix is in the darcs source code repository but I haven't built a new version yet.

I'm working on finishing touchscreen support and fixing a tile bug first. Hopefuily I'll have it up in a couple of days. I've also fixed the problem of the LCD screens sometimes being swapped.

For the touchscreen support I'm implementing the Serial Periperal interface for reading the touchscreen so it won't have to have the ndslib IPC structure hard-coded in. This will allow non-ndslib based programs to work.

That sounds good. Take your time, I'll test it when you're ready.

0.4.3 is up. I've fixed the sub screen issue and added touchscreen support. I tested it on my demo's and they all worked except for the latest space invader version. I think DSEmu doesn't do mode 5 correctly - I haven't looked into the graphics part much yet.

I ran a number of the demo's at ndshb.com and quite a few at least ran. Tic Tac Toe from ndshb.com ran and I was able to play a game which was a good feeling

The biggest issue now is the lack of reasonable graphics support so the next update is likely to be a while away (assuming no glaring problem like last time) while I learn a bit about how DS graphics work.

I've got all DS roms released so far, would you find it worth my time testing them?
