The ARM binary compiled for Yopy PDA works on Sharp ROM with Xqt
¿Can be compiled for OpenZaurus?

Homepage Blassic.org
Source TAR package

There are versions for Linux and Windows too.

Alternately, would anyone be willing to take a look at SmallBasic?

http://smallbasic.sourceforge.net/

To my very untrained eyes, the requirements look promising:

Required:

gcc 2.9x or above
GNU make
Common libraries: readline, pthreads
Graphics libraries:
svgalib 1.9.6 or above
OR
SDL 1.7.x or above
OR
Linux framebuffer (kernel 2.4.x with framebuffer)

Blassic tarball compiled for Openzaurus in the web http://www.blassic.org
Graphics commands with gpe or xqt. Size 2.5Mb with source and examples.
