Re: ASCSI EMUTOS.SYS Bootstrap loader - Proof Of Concept

It sure does. (Not sure why I didn't find the above before I started on mine - never mind - I learned quite a bit in the process). And yours seems to address the issues I'd already noted. Only real difference is where EMUTOS gets written to - I was going for space between root sector and 1st partiti...

Hi (I'm using the SSE Steem Boiler 3.8.2.exe if that makes a difference.) Just wondering if there is a way/how to log the writes to address ff8800?

Re: Help Compiling/running STSpeech.s

I've done a bit of debugging - SMC (self modify code?) is defined as 0

I think its bombing in

Code: Select all

L31cc:	

  move.l	(a0)+,wave_params
  move.w	(a0)+,wave_params+4


wave_params:
wave_a_step:
	ds.b	1


I'm still reading the devpac manual on debugging.

Any help gratefully received!

Thats what I thought - but what I've tried (xenon/eliminator) don't seem to? I guess I'll check my ym loading against st-sound, as I'm probably doing something wrong.

PS The only reason for trying/using win 2000 was that gemxplor has a note saying "xp version comming" (and the fact that under xp, it didn't see the scsi disk at all).

Horizontal Interupt I assumed that for the likes of Spectrum 512 etc, you'd get the interupt when the video had finished ouputting the visable area (the 52us) - giving you the "blanking time" to reset pallets etc BEFORE the next line was scanned (ie the 8 us).

Super Hangon and hatari-1.0.1_windows

Hi

When playing Suer Hangon (doesn't appear to be realted to a specific version, eg klapauzius version, Bladerunners, those in Gamebase ST) - when playing, the background gets "stripes" through it every so often.

Saint does the same, but Steem seems ok...

Thanks
