Hello friends,
Im Sega Master System fan. I noted that any MSX games were ported to SMS like Nemesis by a Korean developer called "Zemina", and others titles were ported (KnightmareII: maze of galious) too. I would like in know what tools are need to start work in something in this area.
Any programmer/developer here is interested in port a MSX title ->SMS?
Hello guys,
I know (and im sorry) this subject is old for you but any member could post here one msx disassembler to see source code in msx games roms?
Thanks
Use the debugger of either openMSX or bluemsx and take a look at the listing. If the game is on a cartridge you can look at the listing in all ROM segments.
I think you can forget the compiling part... There are very few MSX games that you can get access to source code... so... Binary patching it is... It is not exactly fun, but can be a very learning experience for both source and target computer. I've done it for few games I ported from MSX to SVI-328. In the end I even made an AI that does it automatically... That was more fun, but definitely not the kind of project you can take before you've done few ports manually.
If you like to port a game to SMS from MSX it will be a difficult manual labour undertaking. Its either doing binary patching like NYYRIKKI described or make a full clone by rebuilding the whole program from scratch yourself kinda what I am doing. I am affraid there is no easy way.
If in msx pallete 88 is red in SMS pallete red is $03. So i would try modify the code lines with spec differences and compile it.
the value "88" is confusing. MSX1 has no palette registers. It is color 8. there are the colors 0..15.
dont mod all color values, set up sega palette to look like MSX1.
and it will be troublesome on the harsh RRGGBB palette.
better milky colors than oversaturated.
brainstorming a list
r,g,b
color 9 3,2,1
color 8 3,1,1
color 6 2,1,1
color 3 2,3,1
color 2 1,3,1
color 12 1,2,1
color 7 1,3,3
color 5 1,1,3
color 4 1,1,2
color 11 3,3,2
color 10 3,3,1
color 13 2,1,2
color 14 2,2,2
color 15 3,3,3
