Genesis Emulator Port for Nintendo DS

PicoDriveDS 0.1.6

 

PicoDriveDS 0.1.6 is up! Changes:

 

* Added Max Media Dock FAT support (thanks chishm/Bonic)

* Added EZ4 FAT support (thanks cory1492/Rudolph)

* Reduced memory usage, 3MB ROMs should work again

* Added EXPERIMENTAL support for using the additional RAM on SuperCard SD carts to load ROMs larger than 3MB. This comes with the standard warning that this feature may cause file corruption on your SD card. The SCSD may also keep the Genesis ROM in GBA ROM space after a reboot, causing PicoDriveDS to see it as an appended ROM and crash on startup - to fix this issue simply power down, take the SCSD out, and wait a few seconds.

SMS/GG emulator

I have done a lot of work on Osmose 0-8-0. Major changes are new IRQ system, Game option database, and joystick support.But most of the work is not visible. I spent a lot of time to increase Osmose compatibility. Gamegear compatibility is around 98%, and SMS is about 95% i think it's not too bad. The remaining not compatibles roms are games using light phaser (unemulated), game that use SMS2 224 or 240 scanline video mode, and games using exotic mapper (e.g 93c46), or additionnal on board ram, and finally some bioses. Now, only very few rom don't boot at all. Please, note that given the huge number of SMS and Gamegear roms, i can't deeply test every game. If you have problem using Osmose with roms, please, just tell me.

 

What's new in Osmose 0-8-0:

 

-Implement support for zoomed (16x16, 16x32) sprites.

Earthworm jim (SMS and GG) uses 16*32 sprite :/

And a few other one.

-Add support for Korean Memory mapper. Mappers are now method-pointer driven instead of selected in wr8() with if/else condition.

 

-Add row 24-31 scrolling lock.
