As far as I know the AX370 is just a restyled Sanyo Wavy70 which is an MSX2+ machine according to the wiki. Correct me if I'm wrong.
Yes I used to have a Wavy 70FD MSX2+
, it looks the same.
So I think hardware-wise the AX370 is an MSX2+, but it seems they put in the MSX2 ROM, I think probably because they had already modified that with Arabic support.
Ah. Well, I tried my hand at x86 Assembly a long time ago. I forgot most things about it. I mostly only use my MSX for games as well, atm I only have 3 though. Knightmare, King's Valley 2 and finally TwinBee.
A lot of information is here:
