How to load DATs and GRPs onto otyasmilebasic?

I'm learning how to use otyasmilebasic, but I don't know how to load DATs and GRPs onto otyasmilebasic. How do I do this?

I don't think you can??? I mean, I tried to do a test

LOAD"GRP0:TEST"

(file doesn't actually exist) and then

?RESULT
> 1

so, yeah. Not sure what that really means. You can try replacing the default stuff under the "Resources" folder.

Is there a way to load a GRP from a DAT, or convert it into a DAT for loading?

Yeah, just GSAVE the entire GRP and then save the array you GSAVEd with in a DAT file. You can then later load that DAT file into an array and then GLOAD the array onto whatever GRP you want. Not actually sure this all works on otyasmilebasic though.
