First, I have to say that English isn't my first language, so there can be some mistakes. But I will try to explain the problem as best as I can.
I started working on my first rom hack. I installed all things that I needed (Custom Powerups by lx5 and some patches that creator recommended) and created a world map. I tested it on an emulator and everything worked fine. I did it a couple of times. And after I modified it maybe 20th time, when I wanted to test it on an emulator again, for unknown reason the title screen won't show up and my rom just crashed with some garbage on the screen with glitched music in the background.
I copied my map to my "base rom" with all stuff installed and continued my work. After some edits it happened again... ...and it's like 8 times I did this over and over again. My roms keeps crashing no matter what I do.
I tried again with a clean SMW rom, but this time the only thing I patched to my rom was the Raccoon Mario patch. I started my work and made some progress. And after 4 hours of work it happened again. My rom just crashed - it showed "Nintendo Presents" logo, ther it turned black, I hearded some glitched music and whole screen was filled with random graphics from the rom. Then it turn black again.
I tried the same thing like with the previous rom, but I ended with the same effect. After some time, my rom hack is unplayable.
I don't know what causes that and I'm tired of doing the same thing over and over again just to lose everything, but I don't want to give up. Can somebody help me solve this problem? Is this emulator's fault? (I'm using Snes9x 1.51 by the way) Or maybe is something with Lunar Magic itself? I remember that I was using this
button to import my ExGFX to rom and reload it. Maybe I used it too many times?
Maybe I should try download ver. 3.11 and work on this instead of 3.10? I'm really confused...
