To build this, use Build.bat if you're a Windows user, or build.lua otherwise. The built ROM will be called 'Sonic.gen'.
-
For editing sprites you can use SonMapEd, ClownMapEd or Flex2 (Read the issues).
-
For editing levels you can use official SonLVL or SonLVL-64x64-Compatible. Unfortunately, SonED2 is no longer supported.
-
To convert SMPS music to asm format you can use smps2asm.
- S.C.E. uses Kosinski Plus algorithm, but Flex2 program does not support Kosinski Plus Module. Therefore, Flex2.json project file is partially useless. SonMapEd program does not support Kosinski Plus at all. You can only open uncompressed graphics.
-
If you want to convert levels from previous Sonic games, you have to use LevelConverter from SonLVL. Then change the layout format using Layout converter.
-
If you want to make a different text for Title Card, you need to create a file of letters from List.unc. This will be loaded before the level starts. You don't have to add the letters 'ENOZ' (ZONE) because those letters are already in VRAM. Then you have to create a mapping of your zone name in Map - Title Card.asm.
-
If you want to use other SMPS music you can use Valley Bell's SMPS Research or vgm2smps.
- pixelcat — New smooth ring graphics, act 3 and 4 numbers graphics.
- FoxConED — Level Select font graphics.
- Dolphman — Robotnik Head graphics.
