On the subject of pie-in-the-sky hardware modifications, is there any possible way to expand the back-up memory bank in the CD, Duo, or TurboBooster Plus set-ups?
That'd certainly be an interesting project, though a more flexible and/or bigger tennokoe bank would suit the bill nicely. Do any flashcard programs allow you to copy/save data over?
That said, I also started running into problems of running out of space on my tennokoe bank, so I took a day and converted all my save files onto PC & burned them on CD using
nanami's bank. It's a bitch to do, and certainly not the most elegant solution since you have to
manually type in all the hex data on your PC to recreate the save file, but it's a one time thing (for things like saving cleared-game files, etc), and it fits all on one CD very nicely. If you have two tennokoe banks filled up, that could be a weekend project.
BTW, If you or anyone is thinking about doing this, use a digital camera to capture the hex data of your PCE save files. There'd be no way in hell I would've done this if I had to write down all the data by hand,
then manually type all that in again.
