tp99 Challenge

Recommended Posts

Posted (edited)

The last file of every TP99 program loads into the memory top at FD40-FFDF. I suppose this breaks the loader.

I tried it myself.. and it also crashes. Seems there is a dependency outside of the E/A utilities.

 

It appears that after running for a very short time it ends up branching back into the GPL interpreter. Since this is executing Extended BASIC (probably in a corrupted state), it doesn't work very well. It's trying to execute at GPL >0018 (load small capital letters), but it appears not to exit correctly, landing inside the XB ROM. (Perhaps the E/A GPLLNK is not compatible with XB?)

 

When the E/A cartridge is in place, the GPL call returns to the E/A utility. Soooo.. that's probably it. The GPLLNK in E/A's utilities needs to be replaced with an XB compatible one?
