Newbie hacker's problem

If you used both ESE and SonED on the same ROM, then you're not going to get good results. The tools are very incompatible with each other.

 

Have you tried fixing the checksum in ESE, or disabling the checksum check in whatever emulator you're using?
If that fails convert the rom to a .bin if it's an .smd file with smd2bin. That might be the problem...

 

I have that problem too, for a number of things. Rusty Ruins and Wing Fortress (the latter isn't used, so it doesn't really matter) in my hack freeze at the title card (not at a blank screen).

Also, when editing some crap in Metropolis on a clean ROM, it freezes at a black screen after going to the level. I have not used ESE on this ROM, only SonED.

 

I've had the same problem as well, but mine was a little different and I forgot how I fixed it. I also use a combination of SonED and ESEII, I haven't had any problems after I fixed it, pehaps its just the checksum, but be carefull when making the levels bigger. Make sure you have ESE rearange the levels or whatever it does, so that you don't overwrite data when making a larger level, otherwise you will have serious problems.

 

I tried to fix this problem by using ESE first, getting everything I wanted done done and then moving on to SonED. It seems to work for me most of the time. I think it might have something to do with moving the levels. You could just edit the pallettes in Hex by looking at the offset next to the pallette in ESE, do checksum check and then use SonED. If I try the other way around, I get black screen of nothing.
