My goal sometime in the future is to create a 'ROMmable' source to recreate the ROM 03 byte for byte. I am about half done. Then I would be able to test ROM modifications in emulation just for fun since it would never be cost effective to do in hardware. I have been using the gsport emulator and discovered that it indeed does modify the rom in memory to patch some bugs. I then realized if I were to produce a modified rom that gsport would poke in the patches and make it crash. I consulted with David and he indicated where to 'rem out the patches'. After spending almost the whole weekend I finally got a cygwin environment to build gsport. I then rem'd out the patch code and now it leaves the rom alone !!! Now I can go to bed !!!
