I have two Duo-RXs that my TCW2 can save to with no trouble. It's only my Super CD system that exhibits the problem, and it has it regardless of whether I have a Supergrafx or a Coregrafx II hooked up to it.
(And in case you're wondering, it's not just my system. The link above in Japanese describes the exact same problem.)
FYI, the bug is such that if you save and load without turning your system off, it will work. Also, if you check your system memory, there will be a save there even after you turn it off. However, if you attempt to load your save from within the game, it will simply say セーブされていません, which means "not saved". So if you are testing your own copies, make sure you turn off the power and attempt to actually load your game in order to get a proper result.
SkyWelse was kind enough to send me a copy of his TCW1 disc. Sadly, it exhibits the same problem.
The one I just got is FFLTF HE60916-1 TCX2.
PM pending.
Hi Sam, I've got the same as SkyeWelse, "FFLTF HE60916-1 TCW1"
...on the other hand, the last time I looked I looked in your fine country (Japan), it was pretty easy to find these at a reasonable price...
The second thought I had was, "what's the bug, and how hard is it to fix ?"
As long as the buggy versions are common, and the fix is either esily understood or at least available...

Yeah, I messaged a bunch of sellers on Yahoo. Here's hoping they actually check for me.
If the bug is nothing too major, it probably wouldn't be a big deal just to patch the old version into the new version, definitely.
