Since I have screwed up my Prizm multiple times already, I figured it might be best to start putting together a guide for how to fix your Prizm:

If you send an invalid data file to the Prizm, such as a BASIC program with incorrect security bytes, the Prizm will return a Data Conversion error when it attempts to write the data back to memory. The calculator will also relocate all offending programs to another folder labeled Safe-F, which will not show up in the memory manager on-calc. As far as I have been able to tell, the only way to remove files from this folder is to do it manually through USB. The calculator may also delete the Programs folder if all of the programs are invalid. To fix this, simply create a new folder named "PROGRAMS" in the @MainMem directory and delete the Save-F folder.

Occasionally you might get a memory Full error even though you have >9000 bytes of memory left. The only way to fix this is either to remove the program that is causing the memory error or to reset your main memory.

The full mem thing occurs with some invalid programs, but it doesn't appear to be random.

My prizm is screwed up from time to time, I use a LBL 1 and GOTO 1, and it says "SYNTAX ERROR!!!!!!"
This is frustrating, sometimes I program for a few hours, turns out my code doesn't even work. There's no syntax error or anything through the documentation, I'm not the only person with this problem however, other people have ran into it, BS error, I hate it. Ruins everything.

Oh that's the same error I got twice while trying to run  WabbitEmu on my computer when it was stored on my Prizm. However when that happened the first time I still could run WabbitEmu fine afterward.

Does the mem full error occurs when sending invalid files or is it random?

WabbitEmu on prizm???

That might be awesome.

But what was he trying to say? It sounds like he said he has wabbitemu on his prizm.

Yeah that's what I did. It was mainly to showcase how the Prizm can be used as USB drive to run stuff at school or something.
