MESS 150

[+acadiel]

@RasmusM: I do not know whether the MAME core supports the HFE format. If it does I'd still have to enable that format in my parts because at this time I'm only checking for sector dumps and track dumps.

 

Actually, that's me that asked

 

I'm hoping they eventually do, because the HFE format (I'm guessing it stands for the HxC Floppy Emulator) is being used by all sorts of retro systems to work with the HxC - IBM PC, Atari ST, Amiga, CPC, Generic Shuggart, MSX2 format, C64, and more. I'll ping them on their message board as well to see if they know of anyone working on a HFE driver for MESS.

You can use this option in MESS:

-peb:slot3 samsmem

I haven't tested that it's actually working.

Does'nt do anything unfortunately

What should it do?

 

If the SAMS memory card has no ROM, you won't see any difference until you make use of it. At least it provides the 32K memory expected by Editor/Assembler. If the real console shows a visible reaction with the SAMS card, it obviously has a ROM and we need a dump from it.

Still after the SAMS rom for MESS - anyone found it yet?

 

The SAMS card does not have a ROM from what I can see on my physical card.

Not sure this makes sense. The SAMS is nothing more than a bunch of bankswitcheable RAM. It uses CRU-based bank switching. Check out this thread for a description of how to use it in Forth which gives the relevant information on how to operate it: http://atariage.com/forums/topic/180418-sams-support-in-turboforth/

Which program did you test it with? I just tried with RXB 2012 + 'In the dark' and it seems to work fine.

I tried it with Willsy's latest edition of Turbo Forth 1.2 which reports detection of Sams on startup, it reports as present in Classic99 but not MESS 150 with samsmem peb option set which leads me to believe that the samsmem option may not be fully implemented/emulated?

[+mizapf]

Hmmm ... the log tells me that there are actually lots of accesses to the emulated SAMS card, but I neither see any confirmation on the TurboForth screen. Mark Wills should be able to say how exactly TF determines whether SAMS is present.

[RXB]

The DSR for the SAMS is the most easy thing to test for I can think of you just flag the CRU address >1E00 and see if the mapper registers are there or not.

Here is the GPL version to check in RXB:
