So I nabbed the Oasis translation and gave it a whirl. I haven't been able to get interested this game (16-bit), but as I love MSX I just had to see. It's not bad! In fact, I'm pretty f'n charmed. A big part of it is the music, which has gotta be 3x better in PSG form, and the colours and backgrounds just seem brighter & more fantastic.
Then I tried jumping. It's less than perfect. I can't tell just how bad the control is, though, because there's a bug in the patch which won't even let you in the Quarry. I need an image of the original Data Disk 1 to get past this. If anybody's got it, let me know.
I may be able to help you out with that. I've a friend who on the side has repaired many of the buggy Oasis translation patches for Ys I, II and I believe III, as well as a few translation hiccups. I believe it fixes the Darm Tower bug of Ys I as well. I just need to find the files sometime and upload them.
BlueMSX is what I usually use for playing MSX dsk files. Sometimes it depends on the game, but you may have to try inserting each disk into the DRIVE A and running it, as some games may contain an opening sequence that could be on DISK 2 or 3, rather than on DISK 0 or 1. There are even some games that require a combination of disks to start the game, such as Disk 0 in DRIVE A and Disk 1 in DRIVE B and then starting the emulator.
Best to just try all possible combinations until you get your game to start up. Sometimes, it will ask you for a USER DISK, which typically is the last disk in a set usually.
I'm pretty sure there's no MSX/MSX2/MSX2+/MSX Turbo R game that requires two disks in both drives to launch, because not all the MSX models has two disk drives, and I haven't encountered any such games.
Hm.. The MSX Xanadu I have requires that you copy the Data Disk and use it simultaneously in Drive B as the User Disk, or the program gives an error right after the splash screen. It could have to do with that title being released relatively early in the MSX2's life?
Wanderers as I recall is more typical in that you just swap the disks in Drive A, though.
Are you sure that's the only way to launch the game? I'd test that myself, if I had the disk images.
Xanadu is comprised of only one disk. Starting the game with that disk in Drive A will prompt "Drive B Not Ready". A diagrammatic fold-out instructs you to use your own blank disk (640kb), but as I couldn't read the language it took me a while to figure out that it needs also to be a copy.
It's easy enough with BlueMSX by inserting the same file into both drives.
