The boot up screen shows 64KB VRAM as expected (and no password prompt), but how was the seller then showing that 128KB?
DANGER Maybe he borrowed a picture?
The seller has more systems some days.

Yes, i think i can run software from megaflashrom cartridge.

Could you dump the 64k from all slots?

msxholder, I was asking the question on page 5.

Did the seller forgot not to put the VRAM cartridge in the package or is he dishonest?

Maybe it's just an oversight. Popolon should ask the seller to confirm.

Well my guess is indeed some time saving was done and a picture was borrowed (the seller may not have noticed the difference even), it is probably not an intentional misleading.

Megaflashrom disk did not start if i did not press ESC key during boot (to disable the V30 internal drive?).

Megaflashrom (512K+SD) was in first cartridge slot. The saverom dumps can be found from:
https://github.com/popolonx/MSX_STUFF/blob/main/CANON_V30F/V...

And the outputs from various programs:

The cartridge was in front slot, but that is not the slot 1, but slot2. When i put cartrige to the backslot, it is then seen as slot-1

Weird, in slot 3-1 in A000-C000 there is the 2nd half of the disk ROM also visible (next to the registers, as is not uncommon).

Yes, I missed that at first sight, sorry Smile But I got this now covered in the emulation as well.
