Bobble Bubble enhanced

I had never noticed these bugs!

The thing that has always bothered me is the "empty bubbles"

In the coin-op (and in the majority of the home conversions) the bubbles are filled in green

No chances to fill the bubble in MSX2? ^_^

If you guys are busy "upgrading" the game anyway, wouldn't it be possible to use the SCC for music so it sounds more like the arcade and use the PSG for the sounds effects?

I very much appreciate your work, but for me it is hard to take seriously the discussion about wrong pixels while the subject is "Bobble Bubble enhanced" I anyway like your project and I wish you all the good luck! Keep up the good work!

No, I was referring more to the "Bobble Bubble"-part

I mean... You managed to find a wrong pixel in a toe, but you didn't manage to find out what was the name of the game, what an irony, LOL.

KdL, look at this test:

I ran Bubble Bobble with BlueMSX and save the game state when the buggy sprite was displayed. I recovered the contents of the VRAM from state save file to make two binary files. Luckily, the sprites are at the same address as in Basic. So I wrote the following program:

10 SCREEN5,2:COLOR,,0
20 SETPAGE1,1
30 BLOAD"BUB-P0.SC5",S
40 COLOR=(7,7,7,7):COLOR=(5,1,5,1)
50 'A$=INPUT$(1)
60 SETPAGE0,0
70 BLOAD"BUB-P1.SC5",S
80 COPY(0,0)-(255,211),1TO(0,0),0
90 'A$=INPUT$(1)
100 X=28:Y=184
110 PUTSPRITE0,(X,Y),,31
120 PUTSPRITE1,STEP(0,0),,32
130 PUTSPRITE2,(100,102),15,S
140 IF STICK(0)=3 THEN X=X+1
150 IF STICK(0)=7 THEN X=X-1
160 IF STICK(0)=1 THEN S=S+1:BEEP:IF S=64 THEN S=63
170 IF STICK(0)=5 THEN S=S-1:BEEP:IF S=-1 THEN S=0
180 IF STRIG(0) THEN END
190 GOTO 110

The dragon is displayed by sprites 0 and 1 in game. Used patterns are 31 and 32. Other sprites do not contain animation patterns. So animation is generated by patterns copies VRAM to VRAM. I think that at one time it copies the bad partern but I do not know if the problem occurs during the copy ROM to VRAM or VRAM to VRAM. Pattern table and color table are not damaged.

PS: You can add a REM before PUTSPRITE of the line 130 to better distinguish sprites.
