A code-base in pure assembly for developing on these SEGA systems: Genesis, Sega CD, Sega 32X, Sega CD32X and Sega Pico.

• AS Macro Assembler improved by Flamewing: https://github.com/flamewing/asl-releases/releases/ ORIGINAL AS WILL NOT WORK.
  
• Python 3, already included on most Linux distros
  

• Pick your version: linux ("ubuntu") or win32
• Go to /src/tools
  
• Make the folder AS and extract the contents
  
• Build with build.sh (Linux) or build.bat (Win32)

• Basic PRINT text functions, text sizes 8x8 and 8x16
• Multipurpose Object system for easily making your characters/enemies/misc.
• Sprites engine (VDP side)
• Z80 sound driver
• SRAM Support
• Inputs: 3 button, 6 button and Mouse

• Basic ISO file loading
• CDDA Playback: Play, Stop, Volume fading
• BRAM Saving/Loading
• PCM playback: All 8 channels with data-streaming for larger samples *see GEMA Sound Driver
• Scaling and Rotation "Stamps" unstable

• 256-color 2D smooth-scrolling layer with "Super" Sprites --Single SH2 currently--
• 256-color 3D envoriment using model data and 3D-Sprites.
• PWM playback: Maximum 7 channels with both Mono and Stereo samples *see GEMA Sound Driver

All the SCD and 32X features can be used at the same time although for the 32X there's very low memory for storing it's data, specially with the PWM samples.

• Support for the tablet, storyboard and page flipping.

(No sound as it doesn't have a Z80, requires converting the Z80 driver to 68K)

This is a custom sound driver, tracker-based that supports all the sound channels: PSG, FM, FM3 special, FM6 DAC, Sega CD PCM and 32X PWM all at the same time, you can check the progress here: https://github.com/GenesisFan64/GEMA-drv

• All the user code goes to /game, DO NOT MODIFY /system as it will get updated with the latest changes and fixes
• To keep compatibilty to all systems CODE and DATA are separated: game code is stored as "screen modes" (ex. Title, Level...) and the DATA is stored as "banks" and loaded manually depending of the system, this is for SCD, 32X and CD32X.

• This is NOT finished at all and no documentation.
• (SCD) Stamps support is unstable/unfinished
• (32X) 2D-mode might break on hardware if placing too many Super-Sprites

• Support for the Sega Mapper "SSF2" (Genesis and 32X only)
• Convert the entire Z80 driver to 68K for Pico
