- Improved accuracy for G2 bus access for CDDA.
- Fixed CDDA channel restore algorithm.
- Minor fixes and improvements for CDDA.

SOF plays CDDA, but if you chose TMU2 the game will be very slow and show LAN cable connection icon haha If change to TMU1 it's fine, but music in gameplay hangs.

This game shows how loaders are improved now, using 0.6 loaders, it was impossible to run it with DMA enable, and with cdda. Now we have TMU1, and DMA run with this game
I notice too the same LAN picture with TMU2, this game is quite strange, I'm not sure but it is compatible with second thumbstick and it's not a wince game.

with tmu1, musics have issues with DMA enable, without dma for datas, no musics and voices are not good.
Not playable with IRQ too.

Same thing with "behind the loader option" enable.

It's perfectly playable in low level mode, but this mode doesn't check the langage in the bios, it's always in english... It's probably one of the reason why the low mode is so efficient. Do you think it's patchable ?

I've run a number of tests and it seems like stability has improved and there's slightly less distortion. It should be better during online play as well but I'm not tested.

I heard the same shotgun sound with shenmue 2 with cdda, it's probably the same cdda management. But like guilty gear, it's more stable and better cdda quality

Others tests :
kao the kangaroo : still freeze with DMA TMU1.
Zia : not boot with with dma TMU1 enabled. Else run well in SQ. Still distorsion (looks the distorsion is less present with DMA tmu1 than SQ TMU1)
deep fighter : no boot
Virtua cop 2 : boot again with cdda (no boot since 0.8.28) but still rainbow glitches.
Sega rally 2 jap same as before freeze during loading of race 2.

Now the navigation through dreamshell and isoloader is totally perfect !

Just ideas in my noob mind :

Lots of ideas but not enough time in the day.

Probably I misunderstanding and mix by mistake PCM and data transfert but I'm afraid it would be necessary to avoid rainbow glitches with wince game without low level ?

It's still a good idea to made it, but do you think heap features are still necessary ? Now with all your improvements, we don't use them anymore.
If we can reach the boot of sync 0x8c004800 games, for me it deserves a try to remove it.

You can save 4 bytes removing "beta", in the loader text
