Tonton Belmont a updaté son site avec quelques infos concernant M1 & MAME :

M1: Some internal restructuring to get rid of the central game list once and for all. I refuse to let that be visible when the source is opened up 😉 Also fixed bankswitching in the new Raiden 2 driver, which fixed some suddenly-missing tunes in Raiden 2 and also brought Seibu’s « Godzilla » to life.

MAME: CD audio tracks now work for CHD-CDs, so Susume! Taisen Puzzle-Dama has background music. smf is working on the PSX SPU (sound chip) which will get the rest of the sound working in the Konami GV games.
