Re: Use of STKLIM@FA92 when saving files.

Hi,

Not to tread on Andy's toes, but this will work in memu as the emulator monitors calls to AAE for saving and loading.

Running Revenge of the Chamberoids

Hi All, I have having problems running Revenge with the late but one of Memu. I've renamed the second file as default.mtx and included the first file on the command line. However after loading the first file, Memu just scrolls up a "Found: OF THE" message. This did work at some point. Note...

Re: NODE ROM Dissasembly

Hi Bill,

This is all great and the screenshots are great.

For some reason I am not getting email alerts anymore for the boards I am interested in.

Cheers.

Re: Use of STKLIM@FA92 when saving files.

Hi Claus, Changing STKLIM was also used back in the day with sneeky little routines that get called by the USER command. The USER sysvar would be set to something like F920 and the basic loader just had USER. Have you thought about setting USRINT and USERJP (I think) before saving? You might be able...

Re: writing to soundprocessor, need delay?

I can't check at the moment but I don't think the delay doesn't have to be that much, like 4 T-States.

Also have you thought of using OTI instead of OTIR, i.e. no repeat? Typing out aloud, it might decrement B so B would have to be checked for zero after the IN if IN changes the flags.

Re: writing to soundprocessor, need delay?

Hi Claus, I think you can do an OUT (6) followed by a IN (3) which will be enough of a delay. I think the timings are in the manual :) If you have my program that outputs the "Lets go" sample, it might be worth looking at. Never tried to OUT (6) / IN (3) / OUT (6) ... as I always need to g...

Re: NODE ROM Dissasembly

That looks good, thanks for having ago at this. I thought that two instances of Memu could talk to each other. It that right? If so the problem would point at being a handshake (HW/SW?)/parity/dropped character issue. How are you converting DART config to 16550A? Is there any specific part of the RO...

Re: Jet Set Willy Tape Loader

I did wonder if converting some of the Einstein games back to the MTX would be fairly straight forward. Sound and Video would only need minimal changes, Keyboard, joystick and interrupts would be the tricky bits. Thing is when decrypting these files, because the previous loader is known, getting the...
