|
|
- irom: Minor accuracy and documentation improvements
|
|
|
|
|
- irom: Remove use of SRS instruction with AX registers, as those instructions
|
|
|
|
|
do not actually exist

Legal GC/WII DSP IROM replacement (v0.3.1) (0x128ea7a2, 0xa4a575f5)

|

-------------------------------------------------------
|
|
|

|
|
|
|
|
|
- irom: When running from the ROM entrypoint, skip the bootucode_ax branch
|
|
|
|
|
of the bootucode procedure. Since the ROM doesn't set any of the AX
|
|
|
|
|
registers, it could cause bad DMA transfers and crashes.

|
2021-08-17 20:12:25 +02:00
|
|
|
-------------------------------------------------------
|
|
|
|
|
|
|
|
|
|
- coef: Explicitly set 23 different values that are used by GBA UCode, and
|
|
|
|
|
tweaked overall parameters to more closely match those 23 values.
|
|
|
|
|
- irom: Moved a few functions to their proper places, updated BootUCode to
|
|
|
|
|
configure DMA transfers using AX registers as well as IX registers (the GBA
|
|
|
|
|
UCode uses this to do two sequential transfers in one call), and added
|
|
|
|
|
partial functions used by GBA UCode.

Legal GC/WII DSP IROM replacement (v0.2.1) (0xd9907f71, 0xdb6880c1)
|
2021-08-17 20:12:25 +02:00
|

-------------------------------------------------------
|
|
|
|
|
|
|
|
|
|
- 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) (0xd9907f71, 0xb019c2fb)
|
2021-08-17 20:12:25 +02:00
|
|
|
-------------------------------------------------------
|
|
|
|
|
|
|
|
|
|
- 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.

|
- 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.
