Should we ask RetroJunkie if we can get this BIOS dumped? We may have a Japanese v2.21 BIOS on our hands here if he can (if he can find one or has one).
I have asian model and Linguaphone model in hand.I may dump them when I'm free to remake the dump cable and find a computer with parallel socket. But personally I think they are exactly the same in binary.Because the asian model multi-mega in my hand is NTSC.So it's 60Hz+Domestic switch.That makes it works identically as Linguaphone. And I'm wondering if there is PAL asian model multi-mega released?Like in HongKong or in somewhere use PAL standard.
Would you be willing to disassemble it and post pictures of its insides? In particular, the bios chip.
I'm looking to sell it so I'd like to keep everything intact for now. It's an absolute nightmare to open truthfully and I don't trust myself with it. Speaking from a previous experience ofcourse.
I recorded the boot animation and cd player UI of my Asian NTSC model Multi-Mega and Japan (NTSC) model Linguaphone/Education Gear. https://www.youtube.com/watch?v=zw00JJDUrrQ For BIOS dump.I found I have already done that 3yrs ago.I will contact redump or no-intro for releasing it properly. For BIOS emulation.Yes,it's not fully supported by Kega just like CDX BIOS.So it will only be useful for CDX region free BIOS mod.
