Found the exact routine on which Robocop 3 uploads the missing gfx data:

00BEEA: BF 00 80 06 LDA $068000,X
00BEEE: 8D 18 21 STA $2118
00BEF1: BF 01 80 06 LDA $068001,X
00BEF5: 8D 19 21 STA $2119
00BEF8: E8 INX
00BEF9: E8 INX
00BEFA: E0 00 40 CPX #$4000
00BEFD: 90 EB BCC 00beea (-$15)


Seems fine and such, guess it's something to do with vram address ...

Just a note about the Fushigi no Dungeon 2 bug: That's a gameplay bug, not just a graphics bug. The score and floor numbers shown in the screenshot are nonsensical, and the Japanese text underneath (which sums up how the game ended) reads "Defeated by Shiren while carrying the Bizarre Box" which is similarly nonsense (Shiren is the default name of the player character, not an enemy)

The Fushigi no Dungeon games are notable for automatically saving to battery RAM after every action the player performs, so I'm inclined to suspect a SRAM mapping problem, although a CPU bug is also possible.

All those should already be in the wiki. I'll verify they get added if they are not.

Here is a fresh batch. The Wiki isn't loading right now, so I'll leave them here until I can merge them later. The (REGRESS) are items which used to work (based on a 03/30/2010 build):

Bronkie the Bronchiasaurus - Hang after "Wave Quest" screen (REGRESS)
Chibi Maruko-chan - Harikiri 365-nichi no Maki (Japan) - Hang after Epoch screen (REGRESS)
Choplifter III - Rescue & Survive - Graphic Layer Issues
Clay Fighter 2 - Judgment Clay - Hangs at random times (during intro, after a battle) (REGRESS)
Cool Spot - Graphics mess at foot of Cool Spot (REGRESS)
Cosmo Police Galivan II - Arrow of Justice (Japan) - slight flickering at the top while character is being moved (REGRESS)
Hanguk Pro Yagu (Korea) (Korean League)
Home Alone - Hang quickly after displaying in-game screen, music continues playing.
Ippatsu Gyakuten - During introduction, near the top of the screen during the bike race there is a camera which 'follows' the action. It shouldn't move. (REGRESS)
Masters New - Harukanaru Augusta 3 (Japan) - Hang after T & E Soft logo
Otogirisou (Japan) - Hang after Chun Soft Logo, music continues playing for a bit. (REGRESS)
PGA Tour Golf (Japan) - Hang in intro after Electronic Arts (R), music continues playing. (REGRESS)
Pokemon Stadium (World) (Unl)
Primal Rage - Hangs/Black screen when starting to display the Title. (REGRESS)
Redline F-1 Racer / Suzuki Aguri no F-1 Super Driving - During intro, when the camera rotates around the car, there are strips of bad graphics. (REGRESS)
Trinea (Japan) - Initial logo has stripes missing (REGRESS)
Zan III Spirits (Japan) - Hang after Wolfteam logo

Added to wiki..

rev. 7772: [SNES] Fixed clipmasks in hires modes

one more bug can be crossed out

[Linked Image from mamedev.emulab.it]

i.e. Super Moero Pro Yakyuu is now fine (and possibly some other game using hires + clipmasks should have no more glitches in the right half of the screen)

Kishin Douji Zenki - Tenchi Meidou does the following:

D9B831: LDX $18
D9B833: DEX ;X = 0x0000 -> X = 0xffff
D9B834: PHX ;Puts X into the stack
D9B835: RTL ;stack 0xc3 0xff 0xff
C40000: TSB $0c39 ;BSNES returns at 0xc30000!


I'm wrong or it's another in-bank case just like the Rock n'Roll Racing DMA issue?

Hmm. The following program on my Apple IIgs:

CLC
XCE
SEP #$30
LDA #$03
PHA
REP #$30
LDA #$FFFF
PHA
RTL

goes to 030000, which looks to verify the BSNES result.

r7775 /src/emu/cpu/g65816/g65816op.h: Fixed RTL opcode in-bank issue in the G65816 CPU core, fixes at least Shaq Fu and Kishin Douji Zenki 3

Yeah, definitely looks like it. smile

In the other news ... Sound Novel Tsukuru looks weird ... apart that it probably needs an even more accurate timing, but it also sets a V overflow flag in BSNES that doesn't occur in MESS ...

I'm pretty sure Derby Stallion 96 and Sound Novel Tsukuru are mapped incorrectly.
