SofaRun v2.0 bug report thread

Hi Louthrax,

Thanks for making this, have been looking for a good tool to run .dsk off of CFIDE for ages
Ofcourse I immediately downloaded and tested, a couple of things

1) How do I select a different drive letter from the game browser?

2) If ran on a MSX2+ with 256k ram/dos2 whenever I select a .dsk image and start it, the resulting SofaRunIt output is:
[1] name.dsk R
[2] +^| W
Then I press space and it goes to basic and whatever access to disk i make its "Bad file number". Even if it's just an empty.dsk. In this situation there is 160kb of free ram. BTW: My msxdos 2.20 does not have the command memory.. I do have a 3rd party mem.com wich does the same.
If I try this on a 4mb mapper all is ok. Maybe an out of memory error message would be nice

Cheers,

Hi Omega,

Extra drives have to be enabled in the SR.INI file in order to be displayed (that's at the beginning of the file). I've found no clean way to check which drives are enabled or not, so that has to be done manually.

So you confirm that you can launch disks on a CFIDE with 4mb mapper ? That's already great new because I did not test SofaRunIt on this device !

The issue you have does not seem related to the amount of memory, but more to the slot layout. You just need 49152 RAM bytes free, so a 256KB MSX machine has more than enough memory.

Could you try to launch your disk image manually. Just go into MSX-DOS and type "SRI mydisk.dsk" ? By the way, which disk are you trying to launch ?

Ok, this needs to be debugged !

So the non-working configuration is :

• NMS8250 expanded to MSX2+.
• Internal RAM expanded to 256KB.
• Sunrise CFIDE + CF adapter.

Let me know if you have anything else plugged in your MSX (RAM slots ?).
And if you plug an extra 4MB cartridge expansion in another slot, with the same configuration, then MSX-BASIC games/disks are working ?

That's quite weird because "simple" memory layouts (with just internal RAM) should be the safest ones.

I'll try to reproduce that on openMSX (I do not have Philips machines with only 256MB memory !) and see what happens. Please tell me if there's something wrong in my assumptions above.

Correct about the hardware cofiguration. BTW My Sunrise bios is version 2.50.

I'm pretty sure it seems a memory management bug. I have two external mappers, one 1MB one 4MB. I did some more testing:

• RAM in slot 3.2: doesn't work (primary mapper in a subslot)
• RAM in slot 3.2 + 1M or 4M RAM in slot 1 or 2: works (so primary mapper is in a primary slot)
• RAM in slot 3.2 + 4M ram in expander slot 2.[0-3]: doesn't work (primary mapper in subslot)
• RAM in slot 3.2 + 4M ram in slot 3.1: doesn't work (primary mapper in subslot)

I'm not 100% familiar with DOS2 memory management calls, but there should be a call to select blocks from the primary mapper so you don't have to worry about slot layouts at all

BTW: I didn't know there is a Nextor bios I could flash in the sunrise ide

No worries, I won't
