No emulators support loading ldr or bas files directly, because they need to be on a *medium*, like a tape or disk image. Just like on a real MSX.
If you found .bas/.ldr files (mostly loaders, see faq.msxnet.org/suffix.html) they were most likely meant to be run from disk. So, they should work when you put them on a disk image.



If I don't get me wrong, openMSX has a dir as dsk feature, just like in BRMSX, the Brazilian emulator.
If this works like in BRMSX, you could use a Windows directory as a disk image. After booting of the emulated MSX, you must then use the command run"Game.ldr" if the loading file is game.ldr. If you rename this file "autoexec.bas", the game should be runned automatically.

I have indeed (as I think I already mentioned) put the files onto a disk. I did indeed also obviously use a disk rom when trying Gauntlet under the V-20 machine (for which I have the correct roms). However, having put the files to disk, and loading the .bas or .ldr, I run them and either nothing happens or the machine resets.
My original of Gauntlet was on tape, so I'm assuming like with the first reply I got, that it's a custom loader. The disk image I made for it does not work on any of the emulators I have. And I already decided to save those .ldr and .bas files on these types of file as autoexec.bas on the disk. Which works perfectly with a couple of my games, but not with the others.

As the games that are failing to work after being dumped to disk image, I'm assuming these were DEFINITELY the tape versions of the game. So what I'm wondering is..... if I have a bunch of files, starting with .bas or .ldr followed by a bunch of .bin files etc..... is there any way that these can be converted back to a .wav file and then loaded through openMSX on the tape bit? (or a .cas file)

p.s. Manuel, I've read that FAQ, it is in fact how I finally got Feud to work without having to find an emulator that supported those files directly. Disk manager has been very helpful.
I'm wondering though, if mars2000you is correct with the windows directory as a disk image, is it not possible in a future implementation of openMSX to have a windows directory as a tape image? I'm pretty certain these files are from a tape image originally, and have no clue how I can make them a .wav or .cas file again

In some cases, a game transformed in .bas, .bin, .ldr files can't be runned automatically because you must change the loader file, where you can find or add one of these instructions :
poke-1,170 (for a MSX2 Philips)
poke-1,255 (for a MSX2 Sony)
poke-1,0 (for a MSX2+/Tr Panasonic)

You can also need more memory : press on Left Ctrl in the boot sequence of the MSX until you hear a beep

Hmm, right, I totally forgot about the DirAsDsk feature
It puts the files in a dir automatically on a virtual disk image and then uses that with the emulator.

Still, if you found .ldr and .bas files, they were meant to be run from disk. Really.
It might just be a bad conversion or something, though.

What external diskdrive did you use with the Canon V-20 in openMSX? Do other games run from disk with that emulated Canon V-20 with external diskdrive?

I used the Sony HBD-F1 drive for Gauntlet. It works perfectly on the other MSX1 disk games (even ones I had to put to a disk file) with the Canon V-20 machine.

I guess then that I was not meant to play this (and a couple of other) games.

oops Ok. I only just saw mars2000's post about holding down Ctrl during boot.

Worked a treat. YAY!!! thanks guys, yet another one up and running

Or at least until it said "inserta disco en el drive a s y luego pulsa el sepaciador"

I don't speak Spanish, but that looks like spanish, and it seems to me that I have either a file missing or I need a second disk (this was easier on tape <sigh> and it looks like I'm going nowhere until I have the right file/disk and press space

Or I could just make sure I extracted ALL of the files and then press space at the message <blush> (Hey, I did call this thread... BEING RETARDED )

This is also in the "how to get MSX1 software working on MSX2" part of the FAQ I talked about earlier. Note that you're indeed not using an MSX2 there, but part of the problems are caused by using a diskdrive (which eats part of the RAM).
If you have more trouble, maybe you should check that out afterall or again.

technically this is of course possible, the problem is however that disks are randomly accessable and tapes are sequential.
So that would mean that for easy use the *.ldr file must be first and then all the loaded files must be placed in the correct order after each other on the tape. So it would be rather hard to allways correctly guess the correct order, or the user itself must indicate the order.
And then there is the fact of baudrate, if the loader expects a certain speed then that should be made configurable also etc etc, your command line would become extremely long I would say :-)

@turbor

of course, that makes perfect sense, and had I not been struggling so unsuccessfully for so long, would never have uttered such idiocy. The files are in fact originally disk files as Manuel correctly stated.
It was just me using only 5% of the available IQ during this process that had me stumped. Once the thinking cap was on, allowing 21% of IQ to be used, my retardedness subsided and I sorted the problem.
I have since hopped skipped and jumped for joy, and then decided having solved the mystery of that game, to move on to another.

What I could use now, is a crash course lesson in Japanese....
