Title: Is there some software that enables me to find the entry point of a ROM
Post by: Audronic on 06:34, 15 January 16
Hi All

Is there some software that enables me to find the entry point of a ROM (File)
I would like to load a ROM from Basic , and Execute it, as i have done with TFM's ROManager 1.45.

Thanks   Ray

ROManager 2.14 shows the entry points for all RSX commands.
Also the !ROMS command from VDOS does that.


Or you take MAXAM and start disassembling the ROM beginning at &C000. Soon you see a lot of JP &XXXX commands. The first it for ROM initialization, the others are for all the RSX commands (in respective order).

Thanks for that I have seen all the " C3 xx xx " at the beginning of the ROM file. I will try 2.14 as i now have some Extra Flash Ram to do some tests with.
I will also have a look at " VDOS " .


Thanks   Ray
