Ok, I've used the search tool and still can't find an answer to my problem.
I want to run tape games, but the ones I have are in several files, and start with a .ldr or .bas file.
Seems easy enough. However, I need to know what emulator I have to use to run these!! I'm using ParaMSX right now, which allows me to select a tape file, which I duly do. I run the emulator, and up pops MSX basic with Disk Basic. If I type Load "cas:",r I get device IO error. If I type load "feud.ldr" it tells me disk is offline.
I tried taking the disk bios out of the bios directory, but I still get device IO error.
I've downloaded several other MSX emu's today, including RuMSX (which appears only allow .cas files) and OpenMSX, which does seems completely useless and unecessarily complicated. Even the frontend does nothing useful. I can't work out where I should put the rom bioses, or how to point it at the directory where my roms are or anything.
Sorry I'm so retarded, ParaMSX lets me play dumps of my konami carts just fine, but just won't play ball for tape stuff. And even though it's a crappy old mastertronic effort, it's one I enjoyed a lot almost 20 years ago <sigh>
