The 253 chips visually look good. Any easy way of testing for bad ones or stuck ones? I attempted to program a GAL with the S11MOT2A dump available but I couldn't get that to work, no boot. This is my first try at programing anthing, kinda just winging it. I found some matching PAL chips but...

Although the smart option, I am not skilled or comfortable enough in trying a swap at this point. My Board is a Version B, it only has 2 flash chips and has a slightly different layout compared to the other S11 boards I have. I ended up trying a 2A chip from another board and the Game BOOTED...

As far as I can tell it was only point blank 2 and a quiz my angel game that used that chip. All ther other games appear to use the s11mot2a. The file dump available looks like the same for every game? Ideally it would be nice to have the original though.

So I've managed to remove the bad chip and install a socket. I Found some new matching PAL chips but there seems to be little info on making copies or programing these types of chips. I tried using a t48 programmer and Xgpro software with no luck. The software list a handful of GAL chips but no...

Thanks for the info. Figures it had to be something that wasn't an easy swap out. I got a hand full of non working boards with hopes of getting this one working. All the other games use the "S11MOT2A".

Trying to get a point blank 2 working. Currently iv got a black screen and not booting. I tested the top gp-13 board on a tekken and it seemed to work on that board. I also tried the gp-11 from the tekken and it still did not fix the point blank. Only thing I can find that looks odd is a chip...

I found an extreme hunting 2 on ebay. If it ends up having issues, I'll send you a dm.

Looking for atomiswave sega clay challenge and extreme hunting2

Yep, the plan is to get them down to .7v. Yes the first power up screen is very bright and mostly white. I read that someone put potentiometers on the rgb lines to make them adjustable. I think I might go that route as well. I'll probably want to make adjustments when I start adding other games...

I have a multimeter hooked up while it's running and watch the voltage. Probably not the best method but it gives me some readings. On the rgb I can see the voltage go up to 5v occasionally. I got the sync down to 1.1v. Is that too high? Works fine when using the vga. I added some more...

I did some voltage checks. Before any mods, coming from the Atomiswave, Vga seems to be putting out way lower volts on the rgb compared to the jamma. Like .5v vs 5v. The sync is high on both, like 4.4v. So sync may not be the issue. Now I'm thinking when using jamma the rgb's are spiking at...

Complete noob to the rgb modding world, but there was enough info out there to help me get this far. My TV has composite/ svideo only, so not sure a Supergun will help. I could get one and hook to the new rgb lines, but figured I really shouldn't have to. I used 510 ohm with 180 ohm on the...

Hi Everybody, Having an issue when connecting my Atomiswave to a JVC TV that I have rgb mux modded. After some trial and error I managed to get things running by using the vga port on the Atomiswave, splicing into the rgb, ground and sync and hooking that into the new rgb lines for my TV. I...
