Miniplanets
This is the source code for Miniplanets, an unique platformer for Mega Drive where you jump'n'run on small 3D planets (the "miniplanets") in a quest to save Qisha's children and restore the Planelago System back to normal.
You can get a prebuilt ROM here: https://sik.itch.io/miniplanets
This repo now hosts the REMIX Ver. version, which upgrades the graphics and improves the music. If you want to download the last non-REMIX version check commit 104ce86dc5ebc57909019908b2002e872314941e.
Tools you'll need
The shell script has been written for Linux, sorry Windows users!
Though in detail in tools/README, in short you can get nearly all the tools simply by getting the so-called mdtools pack, and the Sona tools from Sona's website (included with the sound driver). Additionally, you're going to need asm68k.exe (for now, hopefully we can replace this with a free assembler soon). Either way, once you have everything just copy the executables into the tools directory.
Sona sound driver
Since REMIX Ver., this game is powered by the Sona sound driver. For the sake of convenience the prebuilt binaries have been included here, but if you want to replace it with your own copy you can get the library here:
You'll need to replace the files in the sona folder with the ones from api-asm in Sona's source code.
Echo sound driver
Prior to REMIX Ver. (i.e. up to REV03) this game used the Echo sound driver instead. Again, the prebuilt binary was included in those versions but you can replace it with your own copy you can get the library here:
https://github.com/sikthehedgehog/echo
You'll need to replace the following files:
data/sound/prog-z80.binsrc-68k/echo.68ksrc-68k/esf.68k
And also make sure to modify the filename in echo.68k to "data/sound/prog-z80.bin".
