Hi All, When I have some free time, I'm still working on the SFX player stuff. Since I've discovered that VICE can emulate the cartridge for VIC20 and 128 too (I am not sure however it would work in C128 mode, or just in C64? Is there any difference, with/without 2MHz mode?), so I've decided to have multi-platform solution, not just C64. It was also easy this way to support Plus/4 too (my program has the "target dependent" parts separated, so support another CBM machine this way only requires some minutes of work - so why not then?), at least on the level that the program would run it. However, AFAIK this hw does not exist for Plus/4, so it's quite useless; the program would run, but no sound for sure because of the lack of cartridge (and also the emulation by VICE, since I use emulator). My question: is there anything like that cartridge for Plus/4 that it's worth to support by me? If there is, can someone give me information how to program it (I/O addresses)? Anyway, even if such a thing does not exist, it would be great to build then, if we forget about the "keyboard" for that cartridge, it's about basically an YM3812 OPL2 chip (well, the older OPL only version for the "real" cartridge, but OPL2 is nicer, and it seems many people replaced it anyway?) interfaced to Plus/4. Of course, eg C16 is also targeted, afaik it's compatible with Plus/4, just having less memory, no +4 softwares (I don't care anyway), and hmm user port, or so, as far as I remember? - Gábor Message was sent through the cbm-hackers mailing listReceived on 2012-02-17 19:00:29
