I wonder if any of these GX games have been made available on console through emulation? if so they may use a build without the protection.

ok so I've identified at least 4 different variants of the VG460 hardware 😵 1. The original Japanese VG460-(A) PCB - This has a large white volume pot, light green traces, black caps and SMD resistors and decoupling caps, PLDs are typically socketed 2. The updated Japanese VG460-(B) PCB -...

When I looked at this last comparing G-Parodius (which has no security chip) to Fantastic Journey (which does), the etc chip equation and tables seemed to simply be implemented in code. Last time I was looking at this I was considering pulling the etc equations out of MAME and implementing...

theoretically several other games could be used for donors for Gokujou Parodius you just need to remove the security chip, I think one of of the Puzzle Dama games even uses the exact right PCB.

Shoot me a PM with a photo of your PCB

Top Post Updated I'd like to get a couple of these boards in the hands of testers before I commit to doing a larger quantity run. If you're in the USA and have a donor board ready and interest in testing let me know. (Sorry to my International friends but if there are issues and a board needs...

I've had this happen before, filled and covered it in a thick layer of black epoxy and ran it. for safety I wouldn't run it without re-sealing it, as arcing can occur through exposed cracks. "glue" isn't enough, you need to seal it. Whether or not this will work depends on the design of the...

Not spefic to target terror but crt gun games in general you want to dial in 5v at the guns if you can also for higher resolution gun games you'll want to crank up the monitor brightness

Amazing work!

supply AND demand are what drives prices. supply is low on these (rare) but demand is also quite low so it keeps the price in check.

I've managed to get 2 sets of these joysticks, I think the first set I snagged for $40 for the pair on ebay, and the second set was around $80 for the pair from KLOV. It's also worth noting that these are the only 2 sets I've ever seen pop up for sale, and if I had seen others I likely would...

send me a PM and let me know what donor game you've got

After diving a bit into the different regional variants of the different games I've decided that the last slot on this multi will have the Japanese version of Karate Tournament the World and Japanese versions both have English language title screen and menus but the voice audio is unique...

both versions had the same amount of RAM. AFAIK only Twin Eagle II used more RAM (and Ultra-X-Weapon, though it was only released as a single PCB unit) the RAM chips are socketed so you can upgrade fairly easily. That wouldn't be the case here, too little RAM would typically cause a no-boot...
