I'm trying to use Nestor's utility to create a romdisk (with an embedded MSXDOS2.20 kernel) to get a standalone version of Tetris 2 Special Edition (T2SE for short).
I use MKROMDSK v1.2 with supplied MKROMDSK.DAT.
My configuration is BlueMSX emulating TurboR with IDE (with harddisk image) and a 4MB mapper.
These are the steps I follow:
1) boot TurboR
2) create a 3072 KB ramdisk
3) copy all T2SE files to ramdisk (they take approx 1,4MB on disk)
4) use command: MKROMDSK G T2.ROM /8
then I extract T2.ROM from harddisk image and give it a try with BlueMSX itself but I never get a fully running version.
Passing through many different tries, I supposed there could be a limit on the size of ramdisk, or on the total size of files on ramdisk, or on the mapper type I choose when creating the romdisk... I did many different combinations but I'm not able to get an "always running fine" version.
Actually I got a working version on TurboR but the same rom produces an "illegal function call" when in basic a simple color=restore is executed... which makes me think I did some mistake somewhere but I don't get where.
Has somebody any experience with MKROMDSK tool?
Any hints?
Thanks
