The msx version is just the Spectum version converted for MSX with a music in addition.
Enemies color has been removed to no longer have the ugly burrs.

I found this trick to run Feud from a .cas image.
Tested on Windows 7 with blueMSX v2.8.2 build 33879.
Feud .cas image from here.
blueMSX default MSX profile comes with a Philips disk drive.
As the disk drives are memory-hungry we need to disable them in some way in order to free up more memory.
One solution is to press CTRL while booting.
Another option is the following:
1) start the emulator with the standard MSX profile. Console shows "23432 Bytes free". The game loads but random chars appear. Stop the emulator.
2) backup file c:\blueMSX\Machines\MSX\config.ini
3) edit the file and remove the following line (we're running from cassette so we don't need a disk driver):
2 0 2 4 65 "Machines/Shared Roms/PHILIPSDISK.rom" ""
4) reset the emulator. Console now shows "28815 Bytes free".
5) game works properly.
Please let me know if this works on your machine too.

Press SHIFT while booting to disable the DiskROM. Should have the same effect Wink.

Or emulate an MSX1 machine without disk drive.

As you said earlier use the Toshiba HX-10 settings on Open MSX and the CAS loads perfectly.

Glad it works on openmsx. On blueMSX, pressing SHIFT (or CTRL) to load Feud from cassette does the job in case of "generic" MSX and MSX2 profiles (just to name two) simply because they default to a ROM memory mapper (66 Normal+Cassette Patch) that supports cassettes. Otherwise the only effect would be to increase the memory (the game won't even load).
Regarding profile "Toshiba HX-10", it has the advantage that it doesn't load a disk drive by default, but its default ROM memory mapper type (20 Normal) doesn't support cassettes. As as a result it won't load the game unless the memory mapper is changed to type 66 (or any mapper able to support cassettes).

If a standard MSX1 game doesn't load cassettes, there's something wrong with the emulator. I guess this is because blueMSX uses a BIOS hack to emulate cassettes. Glad you got it working.
