SF2000 Multicore

About the platform

More information about the SF2000 handheld gaming system can be found here.

Status

Some cores build and work well, others build and have issues (no sound, slowness, etc.), some build but do not currently work, and others do not build at all. For current information on the state of each core, please see the spreadsheet.

Releases

Multicore releases can be found here: https://github.com/madcock/sf2000_multicore_cores/releases

Setup (before building)

(This is the top level project, forked from: https://gitlab.com/kobily/sf2000_multicore)

• choose a directory to contain all this
• decide if you want EVERYTHING (there are a lot of cores!)
  • YES, I want ALL the cores!
    • git clone --recurse-submodules --shallow-submodules https://github.com/madcock/sf2000_multicore
    • wait for a long while
  • NO, I want to select individual cores
    • git clone https://github.com/madcock/sf2000_multicore
    • cd sf2000_multicore/libs/libretro-common
    • git submodule update --init .
    • cd ../..
    • choose a core to grab, for example, picodrive
    • cd cores/picodrive
    • git submodule update --init .
    • repeat this process for as many cores as you want
  • Note: libretro-mrboom takes a very long time to receive, even with --shallow-submodules, so I guess be patient!
• from the top level of this repo, install the compiler tools
  • ./install-toolchain.sh
• copy the 08/03/2023 (official release 1.6) file
  • cp <YOUR_1.6_BISRV.ASD> bisrv_08_03.asd

Building

If setup properly, there are a few ways to build.

If all the core sources for working cores are available:

• ./cleancoresworking.sh to clean only working cores
• ./buildcoresworking.sh to build only working cores

Or use the scripts to clean and build all the buildable cores:

• ./cleancores.sh to clean all cores
• ./buildcores.sh to build all cores

If only some of the core sources are available:

• edit the Makefile as necessary to point to the core(s) you want to build
• the Makefile must include one entry for CORE and one for CONSOLE with an optional MAKEFILE entry
• the easiest thing to do is just uncomment a single core

Optionally, use the Makefile.everything:

• uncomment a single core, as described above
• make -f Makefile.everything

All of the cores are independent.

Updating

• update EVERYTHING from the top level of this repo:
  • git pull --recurse-submodules
  • wait for a while
• you can still pull from individual directories (like a core), as usual, but you may want to grab submodule updates too:
  • git pull; git submodule update --remote

Discussion

All the latest information can be found in the dev channel on Discord which is part of Retro Handhelds.

Notes

This repo was forked from the official repo in github that kobil maintains at https://gitlab.com/kobily/sf2000_multicore I will try to keep things here in sync.
