In the meantime, I tried to convert dsk image in another format (PC99, v9t9 etc), but still without success.
Did anyone ever get to the emulator works with floppy disks or this feature does not work properly in the RPI version at all?
I tried both version one with binaries and other compile from source, but the result is the same.
I'm running out of ideas and I can only ask someone who has this emulator on Rpi2, to try and let us know what happens.
Cartridges work normally, but attaching disk image does not work and I always get the message I / O error 00 while reading dir, or I / O error 60 if I try to save something.
Did you convert the disk controller ROM as well, and is it in the right location? You need to have a ti99sim-specific set of ROMs for the disk controller in the right directory or it doesn't detect the drives. I believe that leads to I/O error 00 when trying to load something.
From the readme:
If you want to use the disk emulation features, you will need to create another cartridge named ti-disk.ctg that contains a copy of the TI Disk Controller ROM (the section on convert-ctg contains information about creating cartridges for peripheral DSR ROMs).
To create a DSR ROM cartridge, simply use the --cru=xxxx option to convert-ctg. This will instruct convert-ctg to store the ROM at the special DSR memory range, and mark the cartridge with the correct CRU information. In order to use the disk emulation features, you need to create a cartridge from a TI disk ROM with the name ti-disk.ctg with the CRU address 1100.
If you've done that, perhaps there's a problem with the original rom file?
