Bass, I remember I sent you some cooked roms without F4 and RTC some years ago. Have you ever used those somewhere?
*PS* Now that you finally returned to the community, how about converting my FS-A1F to 2+? I happen to have a 9958 vdp lying around in a drawer somewhere... Maybe some RAM increase as well! Smile

I'll send you an email. Rgds.

I already have created such roms for a user on this forun. If you like I can share it with you as well.
