Sega Saturn Emulation

inukaze opened this issue · 3 comments

Hi there again, i had some troubles emulating Sega Saturn with the cores
some days ago i had posted i can use anymore "YabaSanShiro" and i ask "How i download & Compile Yabasanshiro"

Well right now i am trying with another cores like "Kronos" well is 51% more slow than Yabasanshiro but works.

Dunnos with all cores use "Bios" can support "Languages"
¿ How i can set by default for all that cores the language is "Spanish" in case they have in the options ?

¿ Why no all that cores have "Auto Frame-Skip" ?

Right now i try to emulate some games for Europe
"FIFA Rumbo al Mundial 98" (Version for Spain / Europe)

in the terminal i saw the follow output multiples times :

R0 =  00000000	R12 =  00000000
R1 =  FFFF8888	R13 =  00000000
R2 =  FFFFFE10	R14 =  06000FEC
R3 =  FFFFFE15	R15 =  05F47924
R4 =  00000194	SR =   000000F1
R5 =  0600CFC0	GBR =  FFFFFE00
R6 =  E0000000	VBR =  06000400
R7 [libretro ERROR] Yabause: Slave SH2 invalid opcode

Yabause Core Output :

R0 =  00000060	R12 =  00000000
R1 =  FFFFFE11	R13 =  00000000
R2 =  FFFFFE10	R14 =  06000FEC
R3 =  FFFFFE15	R15 =  05FCC3FC
R4 =  00000194	SR =   00000060
R5 =  0600CFC0	GBR =  00000000
R6 =  000045E9	VBR =  06000400
R7 [libretro ERROR] Yabause: Slave SH2 invalid opcode

Bettle Saturn works with this version of FIFA :D.
Dunnos with Bettle Saturn

1 - ¿ Why in the options not exist Auto Frameskip like in Yabasanshiro?

2 - ¿ Why in the options not exist Share Internal Or External Ram with another Cores of Sega Saturn ?

With "Independence Day - The Game" (Europe / Multi 6 / Version 1.000) if i want sound i must enable "Force HLE BIOS" because with the Saturn Saturn BIOS using Kronos i not got any sound / music of game.

with NBA Live 98

Kronos :

Bettle Saturn (Mednafen Sega Saturn Module) :

Well with Panzer Dragoon Saga i guess this in the background its a glitch :

You'll likely want to make this issue in the bettle core issue queue.

RobLoach with Bettle Core this issue don't exist, just with the another like YabaSanshiro, Yabause & Kronos, happend this issue.

@inukaze please close this issue as it is not related to compilation issue with libretro-super.

Moreover, it will better to ask your questions first on the forum or discord and if there is an issue with the core please open an issue in the repository of the core either beetle-saturn-libretro or yabause.

Thank you.
