SPS Customizer
Java mod listed for Minecraft 1.21. Downloads from the MC Java Mods app on Android.
⬇ Download on ModrinthAllows Mekanism's SPS to use custom recipes through JSON. Still a work in progress — I plan to fix bugs and add missing features.
Note: I spent 3 hours looking for a mod with this feature, couldn't find one, so I made it myself :)
Example:
{
"type": "spscustomizer:sps",

"amount": 1000
},
"output": {
"id": "mekanism:oxygen",
"amount": 1
},
