Re: WIP Atari ST ScummVM-lite

I tested scumm_st_alpha_200531.zi on my Mega STE (4mb, 2.06 german tos, using Cosmosex) with DoTT and MI2; herewith my findings when selecting: #1 (YM) for sound and #2 (DMA Sound) for speech/effects. - DoTT: intro + game works, with YM background sound; no speech or sound effects heard - MI2: intro...

I've built a couple of DRAMduinos, they're cheap and easy, though they only cover 41256 & 4164 chips
Wouldnt that cover all of the ST 32kb DIP memory modules?

RAM DIP Tester

Hi there,

I have a bunch of ram chips, of which I guess some of them are not working. Is there a modern stand-alone way to test individual chips?

Kind regards,

Re: WIP Atari ST ScummVM-lite

This is very interesting and fun! How realistic is it to hope for a stock 4mb STE version?

Re: Atari Mega ST Video Output problem

Hej guys, Ive replaced the Electrolyte Capacitors around the circuit and reflowed the shifter pins. Ive also checked continuity between GLU/MMU/SHIFTER for the DE, and they were fine. I had the idea of connecting the board to ST HIGH, and this also gave me screen for a period of time, before becomin...
