Ok, I've learned a lot more about hacking since the last time i posted questions on newcomer board but I'm still pretty clueless.
Right now, I'm hacking NES Metal Gear (once again) to be more faithful to its MSX counterpart and here's what I'm attempting to do.
1. Learn how the game recognizes a given tile as a floor tile, a solid tile, vertical door tiles, horizontal door tiles and locked door tiles and be able to change them.
2. Modify the placement of a truck exit, ie, where Snake shows up outside when he walks out.
3. Spawn sprites of my choosing and choose where to spawn them.
Does anyone have any suggestions on what area of hacking I should look into first?
I have beginning assmebly knowledge and have used hex editors and tile editors but past that, Im lost and It doesnt seem like at least #1 would be all that hard to accomplish.
Anyways, thanks for any helpful response in advance! If I ever get this done, It will be because of you!
