So I removed MSX2 MAIN BIOS from its slot and replaced it with the MSX1 BIOS. Nothing more, nothing less, and it worked fine (althought there some changes in the keyoboard layout).

This is the one that I want to know :)
Did you change only main-ROMs?
I think that both Philips (VG-8235 and NMS-8245) have the same slot configuration, but my VG-8235 has that annoying memory bug (any solution to fix this?). This is it, BIOS in slot 0, slots 1 and 2 connected to cartridge entries and extended slot in slot 2, with DISKROM, SUBROM and memory.Do they have the same memory (slot) configuration?
Yes, but you need a "patched" MSX2 BIOS. The original BIOS needs the Clock IC, but you can find patched versions that do not need clock at Hans Otten's page. http://www.msxhans.msx2.comAnd another question: Can MSX2 be booted without CLOCK-IC? (Please break the clock chip of your MSX2, and let me know the result if possible ^^)
Look at the SVI-738 page, there are some BIOS variations to do the MSX2 upgrade. They should work fine for you.
