I am newbie for NES development and still cannot successfully port the software on disksystem.
Tapedump 1.0 and fds writing extension which are developed by ccovell can be found in link below:
viewtopic.php?f=2&t=9909
Tapedump 1.0 do not include disksystem fds format file and fds writing extension do not include dump function, so I decided to port tapedump 1.0 to disksystem by myself.
Since tapedump use memory address of 0x8000 and 0xE000 for program and 0x0000 for character data, I replaced program on 0xE000 to 0xA000 to release 0xE000 for disksystem bios.
In TapeDump.asm, I modified line 105
.bank 3
.org $E000
to
.bank 1
.org $A000
I also replaced vector address from 0xFFFA to 0xDFFA by replacing line 837 from
.org $FFFA
to
.bank 2
.org $DFFA
Compiled tapedump using nesasm and copy pasted compiled Tapedump on writing extention fds file without destroying fds file structure.
Ran tapedump fds on Virtuanes emulator + disksys bios. Bios boots perfectly and confirmed that all programs are placed on right memory position by looking at memory dump window but I get error when tapedump is just begin to boot.
Copy pasted compiled nes file to fds format file.
Bios boots fine but I get error on next screen.
Getting error. Sorry, error description is in Japanese.
Is there any tapedump fds file(not writing extension) available on any website?
Is there anything else I need to add on TapeDump.asm to run tapedump fds on disksystem?
