Legal GC/WII DSP IROM replacement (v0.2.1)
|
|
-------------------------------------------------------
|
|
|
|
- coef: 4-tap polyphase FIR filters
|
|
- irom: unchanged
|
|
|
|
Coefficients are roughly equivalent to those in the official DROM.
|
|
Improves resampling quality greatly over linear interpolation.
|
|
See generate_coefs.py for details.

Legal GC/WII DSP IROM replacement (v0.2)
|
|
-------------------------------------------------------
|
|
|
|
- coef: crafted to use a linear interpolation when resampling (instead of
|
|
having a real 4 TAP FIR filter)
|
|
- irom: added all the mixing functions, some functions not used by AX/Zelda are
|
|
still missing
|
|
|
|
Should work with all AX, AXWii and Zelda UCode games. Card/IPL/GBA are most
|
|
likely still broken with it and require a real DSP ROM.

Legal GC/WII DSP IROM replacement (v0.1)
|
|
-------------------------------------------------------
|
|
- coef: fake (zeroes)
|
|
- irom: reversed and rewrote ucode loading/reset part, everything else is missing
|
|
|
|
Good enough for Zelda ucode games (and maybe some AX too):
|
|
- WII: SMG 1/2, Pikmin 1/2 WII, Zelda TP WII, Donkey Kong Jungle Beat (WII), ...
|
|
- GC: Mario Kart Double Dash, Luigi Mansion, Super Mario Sunshine, Pikmin 1/2, Zelda WW, Zelda TP, ...
|
|
|
|
Basically... If game is not using coef and irom mixing functions it will work ok.
|
|
Dolphin emulator will report wrong CRCs, but it will work ok with mentioned games.
