Just for your perversion ? Why not using the flash cartridge?

I think that the conversion problem comes from the fact that this 48 Kb ROM does not have the 41 42 signature at the beginning of the file, but at address 4000H. The zone between 0000H and 3FFFH is probably used for some data and routines.

So, I guess the conversion needs to be made in 2 steps :
a) remove the part between 0000H and 3FFFH and convert the remaining 32 Kb ROM
b) remove the part between 4000H and BFFFH to get a 16 Kb ROM, add the 41 42 signature to this part while removing empty bytes at the end and convert this 16 kb ROM

If it works, then the remaining problem will be to find the link between the files produced by the 32 Kb ROM and the file produced by the 16 kb ROM.

I have made a loadable version of the game as a disk and cas image. Can i post a link to them, or is that considered piracy? The ROM download was free, so i'm not sure Wink

Artrag, cassettes are for nostalgy. Smile For me the using of flash cartridges is some sort of perversion. Wink At the weekend I loaded a handful of old cassette games which I had never played before and that was fun! Smile

The rom works with odo from disk.
Technically it is piracy even if the rom is for free.

Anyway feel free to do a cassette version provided that you do not alter titles or game elements.

The 64KB version is sold. The 48KB is free.

piracy? the rom is FREE, the game is a perfect clone of an existing game (did they payed the royalty?).So if i download that rom for free and use it in my msx is ok , but if i made a modification to it for PERSONAL USE (no internet redistribuition to anyone) is it PIRACY? i don't belive this
