I've been missing being able to run Colleen on my phone at all since as of a few years ago Google Pixel phones can't run 32-bit programs and there haven't been updated builds of Colleen in ages. So, I took to compiling it myself. I was able to get it to compile, in 64-bit, using a much later Android API level than it was written for, and it runs...but, file access is broken so I can't actually run anything besides booting into the built-in Altirra OS. I'm sure it all has to do with the security changes. I'll work on fixing it as time allows. Unless someone else out there has already done this.
