Picp works with older versions of PS+ firmware, but the protocol is not the 
same. Your hex file contains two blocks of program data, one starting at 
zero, and one starting at 1000 hex. PS+ firmware prior to 3.00.40 expects the 
set range command to contain two bytes of address (always 0 since the code is 
assumed to always be in one block starting at 0) and two bytes for size. 
Starting with PS+ version 3.00.40, set range is sent as three bytes of 
address and two bytes for size.

The result is that your second block of data overwrites the first block 
starting at address zero, thereby "garbling" the data.

The quick solution is to download and install the latest version of PS+ 
firmware. If this is not practical for some reason, I can modify the picp 
source to handle your situation, assuming that older PS+ firmware will accept 
a non-zero address in the set range command.
