My software doesn't pad anything, since erased (flash)EPROM already has FF in unused places...
The padding could still be required, your eprom would be performing the 'padding'.
What in the Genesis would require the padding? The checksum is software only. And would be affected by the padding ...

The genesis hardware need a 128 KB size alignment or your rom won't work correctly. You said objcopy do padding, can it does size alignement which is somewhat different from padding (padding just fill until you reach the pad size where alignement fill until size align).

There a lot of tools to develop for ARM without having to purchase any hardware:
There's QEmu Arm (http://fabrice.bellard.free.fr/qemu/), skyeye (http://www.skyeye.org/index.shtml) and, the Rockbox simulator (http://www.rockbox.org/). There's also GBA and Nintendo DS. All of these support for GDB ...

256x192 seems too much limited for safe area. When I worked in game company where we made games for NTSC TV console, we had safe area 288x216 and text safe area (where text is surely readible) 272x202 in 320x240 resolution on 14''..21'' CRT TV's.
I think, I must check some games to get statistics ...

That's a beauty! Thanks.Chilly Willy wrote:How about
Code: Select all
org 524287 ds 1,0
It won't work with a defined value though:
Code: Select all
ROMSIZE = 524288
ORG = ROMSIZE-1
DS 1, 0

asmx and padding?
Can padding be handled in asmx?
I tried:
ds 524288-*,0
But, this only works up to 1024 bytes, due to the MAX_BYTSTR define. Upping the size of the MAX_BYTSTR would work, but there has to be a cleaner way.

Here's the equivalent area for NTSC:
This is based on:

And agrees with 8bitwizard's 256x192 for anything important.

Echidna data linker
This isn't as useful for the Geneis, but could be useful for the Sega CD/32X, Saturn or, Dreamcast:
