Changelog
v2.0.2
- Fixed ARGV support..
- Corrected remaining instance of PicoDriveDS to PicoDriveTWL.
v2.0.1
- Fixed a derp where the Slot-2 bus owner isn't set to arm9, so the MEP couldn't be used.
v2.0.0
- This is now DSi-compatible, as the name has been changed from PicoDriveDS to PicoDrive TWL, picking up from the original source code by Ryan FB.
- Added screen filtering. The screen will now look less pixelated.
- MEP/DSi: Implemented SSF2 mapper emulation.
- Super Street Fighter 2 and other ROMs (such as hacks) that uses the mapper, now works.
- Tried to fix the emulation speed going too fast in some areas, due to less sprites being rendered.
- Screen is now correctly adjusted for H32 mode.
- ROM size limit has lowered from 3MB to 2.5MB, as the arm7 binary in RAM has moved to main memory. This does not apply to users with a memory expansion pak, or a DSi console.
