 |
|
Bouncing back from another thread...a little question regarding copiers' UI in general:
It seems the SMD's UI is coded in z80 mode and most SNES copiers' UI in 6502 mode.
From memory, only the SWCDX and SWCDX2 make use of the full SNES palette.
Why such a choice?
Were the MD and SNES not well documented at the time so developers preferred to stick to older processor development?
Was it an EPROM limitiation (size/cost/production)?
Hardware limitation?
BTW I remember having read somewhere the SWCDX's interface was made by Pan/Anthrox, any detail about that story? Is the source code out there somewhere or Pan just provided the tiles? |

For the MD, price was probably a big factor. 8-bit ROMs are much cheaper. Free/cheap Z80 assemblers were also likely more available, opposed to 68K which are still not very available. There weren't any homebrew documents back then and the SMS VDP mode would be easier to reverse engineer too.
There isn't any reason all SNES copiers couldn't use more colors, they were just lazy. |
