Hello all. I'm about to send out the Sound Expanders promised to various people, but unfortunately I have lost my X1541 cable so I couldn't upload the Composer and Editor programs, both of which need cracking. Rest assured I will do this after the weekend, as soon as I find that cable! I have also entered the first movement of a Beethoven sonata into the Composer, which uses a Grand Piano sound (sort of) so you will have some nice music to listen to. Anyway, in an attempt to find some *SOFTWARE* to run on these expanders, I did some research into the MSX computers and the Sega Master System, and it seems there's a wealth of FM-enabled games out there, mainly in Japan. I am going to rip the sound routines out of my favourite Master System games and write a player for the C64, but first I need to find a YM2413 chip. Does anyone, probably in the Netherlands, have access to an FM-PAC for the MSX (or any MSX 2+ computer with MSX-MUSIC built-in), or even a Japanese Sega Master System? The interesting thing is that YM2413 is OPLL, or really low cost FM, but it seems you need YM3812 OPL2 to emulate it exactly. YM3526 as found in the standard SFX Sound Expanders doesn't include the waveform select bits, whereas the cheapo OPLL uses one out of the two waveform bits, ergo you need a YM3812 upgrade in your Sound Expander to hear my Master System tunes emulated exactly. Not that it will make a great deal of difference, though, as a normal YM3526 will still play the tunes better than any PC emulated YM2413 can :) I need a YM2413 to extract the instrument table data from the internal ROM, and this will be useful for MAME arcade emulator writers as well as my own projects. So, does anyone have an FM-PAC or an MSX-MUSIC machine? Richard - This message was sent through the cbm-hackers mailing list. To unsubscribe: echo unsubscribe | mail firstname.lastname@example.org.
