Hello everybody!

I'm looking for schematics of A1FX, and some tutorial or procedure to add internal FM.

In my case I already have the YM2413 in place, yet the games (F1 Spirit 3D Special, Laydock 2 ,...) not detect the presence.

Thank you!

Yes, you need to add the ROM. MSX-MUSIC is detected via a string in the ROM: APRLOPLL or PAC2OPLL (for FM-PAC).

is it possible to put 4 mb in the a1fx? mine was upgraded in the store when i bought it to 256 k inside, when i then put in a memorymapper from checkmark, i had to add a switch on it to put on / off the memory mapper of 512, so i could use the 768 memory (look under the tastature, there is allready made space for 2 x 4 mb. ..
