Sorry for the late reply. I've been busy with IRL matters, and in a few minutes I will have to step away from the computer again.
Here is a sample image of what I am trying to replace the title screen with:
Eventually, I'll write up in detail how I inserted this into the game, and post a Fraps ePSXe recording of the failure. I just have a bad headache right now.
Thank you for offering your help! I wish to learn more about FF7 hacking, even if it is difficult.
Hey NERV Agent, no problem IRL matters should always come first
Anyway onto the matter at hand, i tried replacing the image just as you did and i saw what you mean, most tim converters produce a TIM that makes the screen either flicker or just black, or if you use tim2view it just uses the old cult and makes the wrong colours appear (but the image does display), after a few hours of testing i think i am getting close to a way of getting it to work (just need to run a few more tests), i will edit this post shortly if i am successful.
OK i think i have got it fully working now, i would need more test samples to be sure but it seems to be working, i think i figured it out, other images aren't working by default because when you change the TIM or make a new one you change the CULT and IMAGE VRAM, these need to be the same for the image to work correctly, so after editing the TIM to have the same as the original it works fine
, so just make sure once you made a TIM image that the CULT and IMAGE VRAM settings are the same as the original (they are displayed in tim2view at the bottom left once you open a TIM).
Here is the example you posted above converted to TIM that works in FF7. (below is the opening_17.bin of the picture you posted BEFORE LZSS compression)https://www.mediafire.com/?w69uhi9kar6ts7i
Hope that helps.
