Pour la c-board, tu veux dire que suivant la révision, il faudra effectuer une modif ?
Alors si tu choisis de remplacer la rom programme comme évoqué précédemment, la modif sur la C-Board sera la même quelque soit ta révision
. Globalement tu peux regarder ici →
http://www.arcadecollecting.com/dead/dead.html. Tu y trouveras la rom décryptée ainsi que la procédure à suivre. En l’occurrence, concernant la modif de la C-Board, il faudra enlever la pile, couper deux pistes et connecter deux PIN du B-21 au 5v.
Bref, c'est pas la mer à boire

La procédure plus en détail :

To fix your game, download one of the patched sets below and take a look at the file names. Find the EPROMs on your board that correspond to the file names and burn the new data onto an EPROM that is the same size as the original. Remove the original EPROM(s) and put the freshly programmed EPROM in thier place. Now you'll need to make some modifications to your c-board. First remove the battery. Next, locate pins 45 and 46 on the CPS-B-21 chip. You'll notice there are tiny traces connecting these two pins to ground. Carefully cut these traces with an exact-o knife or whatever works. Don't cut the nearby traces. After cutting, it would be a good idea to measure resistance from ground to these pins with a volt meter's ohms setting. If there's still a connection, you'll get a reading of near zero ohms resistance to ground. However, once severed, the pins still won't read open because of the CPS-B chip's internal connections. You should read a few mega-ohms of resistance to ground. If you are working on 3 Wonders, or a similar c-board, you may think there are no traces connected to pins 45 and 46 to cut. They are still there, they are just connected to the pins from under the chip where you can't see them. You will have to snip the bottoms off those pins, leaving enough to solder to. Do not connect +5v to these pins until you are sure they're no longer connected to ground or you will be making a very short path from +5v to ground and smoke and fire will be sure to follow if you apply power. Once these pins are cut, add a blob of solder to the two pins and run a wire to a nearby source of +5v to pull them high.

, on ne pourra donc pas tester ça ensemble. Je vais déjà regarder si j'ai encore des GAL correspondants (si je ne donne pas de nouvelle n'hésite pas à me relancer
