isx2gb v1.02

Command line utility to convert Intelligent Systems eXecutable files into Game Boy ROM format. This is my personal replacement for abISX v1.02 by Anaerob. It has following features:

• code / data overflow in bank 0 is allowed, excess bytes are moved to bank 1 without any fuss.
• you're not forced to ORG your code/data if you don't need to, just GROUP it in appropriate banks.
• you can ORG your code in RAM or SRAM (why not?) and use -r option to save it to file for further processing. This might be appreciated by ROM hackers while generating series of patches.
• to create symbolic file use CAPSOFF/SMALL with PUBALL directives in your source(s).
• ROM checksums are fixed automagically providing that there's a valid logo in header section.
• ROM map is more readable.

Options :

-f  switch ROM filling pattern to 0xFF
-p  round up ROM size to the next highest power of 2
-r  save isx records separately
-s  create symbolic file for debugger

Important :

Let me know if you see similar message:

Error: Unknown record type (1417 : 14)

Currently only record types 0x01, 0x13, 0x14, 0x20, 0x21, 0x22 are supported and that should be enough.

To do :

• improve rom padding option
• clean up code / comments
• test it thoroughly

Bugs :

I've fixed every one I found. Let me know if there's any more.
