« on: January 06, 2016, 04:41:23 pm »

Hello all, i have a little problem with the Y-Pos of one game, Resident Evil 3 : Nemesis (PAL-FRA).

The game is Libcrypt protected and i need to patch it with PARADOX patch, and this patch have a cracktro, you can select PAL or NTSC before play and the problem is here, the game is a PAL version and when i boot it NTSC, the image is a little too down on the screen... I've try to correct that manually but the patch use is own Y-Pos setting, nothing to do with the original Y-Pos code, it have no effect... Any programmer here can look how the patch work and center the screen for the NTSC?? Any help will be realy apreciated.

0A 00 24 86 02 00 40 14 13 00 90 24 10 00 90 24 0E 00 22 86 00 00 00 00

PAL COVERT (P4U+Z2K):
0A 00 24 86 02 00 40 14 00 00 90 24 00 00 90 24 0E 00 22 86 00 00 00 00
