Now there's a reason to build 1Mb FlashROMs... Hannibal

Thanks guys!

Updated the diskrom; fixed loading into page 1 (thanks Ramones!) and switched to
ASCII8 mapper (still write to the KonamiSCC mapper address too though, so it actually supports both).

I have tried Undeadline and Sonyc in a 1024 MegaFlashROM and it works flawless!
Vincent, thank you for this amazing diskROM!
Now it is possible to make ROMs of games like Bomb Jack, Pang, Sonyc and lots more Smile

@Vincent van Dam
Great Work!! Greetings and thanks ror sharing it.
BTW Can I give you a suggestion?
Add compression!
Use something like pletter to compress each sector
or group of sectors and put decompression in
the DISKROM.
A lot of disk games would become accessible also
for 256K expansions

Compression: great idea! It will probably still be about as fast as a normal floppy! Smile And it might be enough to fit most 720kB games in a MegaFlashROM SCC with 512kB... (which is standard).

And to offer a retrofit for the 512 SCC model, for a small fee of course Tongue

I like the compression idea, working on it! Running Naked in a Field of Flowers

(I'll make it hybrid again, supporting as it is now, but with a custom pc tool to convert dsk images with compression applied to it.)

Look for pletter by XL2S,
you'll get a nice PC compressor (with C sources) and a light z80 asm de-compressor

Vincent: great! Please publish C sources, so that it can be used on our beloved Linux systems as well Smile
