[Coco] Barry's romdump program

[rietveld rietveld]

I dumped the rom as a 16k.   When it was done I ran 'PRGFLASH.BAS'.   Typed the name CASTLE.   The computer just locked up and displayed random characters.   I thought that I needed to convert the bin so I tryed coNv2bin.   When I entered the name of the dumped rom. 'castle' it said the bin was greater than 16k and needed to be split?   Even though the dump was set to 16k?

I am testing mine anyway and yes it does seem to be working (so far) with my CoCo SDC,  it is a little less than half way done right now dumping Mind Roll, a 32k banked cartridge. Anyway, I am confused, you say “I used your dumper on my ROMPAK copy of the game and it made a dump that was a bit bigger than 16k”? That should be impossible as the command t uses to save the dump is:
SAVEM “DUMP”,&H4000,&H7FFF,&H4000
This saves exactly 16k of memory starting at $4000 hex. Each 16k segment of the rom is saved that way. I don’t know how that could create a file any size other than 16k. Mind you, it will have a 5 byte CoCo header and a 5 bytes CoCo trailer standard to all CoCo bin files. It should be loadable into a CoCo Flash as a 16k bin file with no conversion needed.
