I got a PC Henshin (the one with just PCE on TG16 compatibility, not TG16 on PCE) from Tototek a little while ago, but Sapphire keeps freezing on me right before the yellow crab tank boss in the 1st level when I use the PC Henshin with my recapped Turbo Duo + Arcade Card Duo, but works fine in a DUO-R + Arcade Card Duo (without the PC Henshin).
No problems (so far) whenever I use the PC Henshin with other Arcade Card games or HuCards. Tototek wasn't able to help and I never got a response from DB Electronics (which is fair enough since he didn't make the one I have, just designed it).
Anyone see anything like this before? Not a huge deal since both my Turbo Duo and Duo-R are RGB modded, although the Duo looks slightly better.
