Summary	02181: wilytowr, atomboy, atomboya: Bad gfx1 rom.
Description	In the score counter is the character number "3" corrupt (see Score.gif). This is since the romset was added in MAME 0.61. If you compare the gfx1 roms wt_b-5e.bin and wt_b-5f.bin (see GFX1-5e+5f.gif), you see that every byte in both from $0000 - $018F are identical, except $001A and $013E. If you changed address $001A to $60 like in wt_b-5f.bin, the number "3" looks ok again. Why the address $013E is different did i not found out! Another grahics glitch can see on the title screen and after INSERT COIN (see InsertCoin.png). The baddump flag must be set for wt_b-5e.bin.

No.02285 Stefan Lindberg Senior Tester Sep 1, 2008, 04:02	Judging what it says in the source then i guess it's a BTANB. Also i can't make that insertcoin bug mentioned happen (i use 0.127u1)?
No.02287 Tafoid Administrator Sep 1, 2008, 04:37	I see the dash crediting up in wilytowr, but since it's basically the same color as that area in the main game, it's hard to notice.

No.02298 Stefan Lindberg Senior Tester Sep 1, 2008, 18:25	I just checked and the insert coin bug do only appear in "wilytowr" it seems (0.127u1). My PCB does not show that glitch as it's the Atomic Boy i have :-)
No.02319 Haze Senior Tester Sep 4, 2008, 06:28	the corrupt '3' etc. is correct, it was confirmed on a real board long ago. It has been dumped from many boards, and does not require redumping. MASH, PLEASE stop making fake roms, you're not helping, creating a 'fixed' rom is only going to confuse things if people start putting it back on their PCB. waterski is another game with confirmed corrupt characters (bad pixel in 7) which is the same on all original PCBs. Mistakes happen.
