Well, I'm stumped. I've been struggling to upload modded software but I keep striking out. I've read through the entire navtweak thread and I think I've tried everything.

I'm running a Mark IV Nav with V32 software. I've modded the V32 Navboot splash screen, car icons, and warning screen text using Navtweak. I've also changed the 4th bit in sw_rel.tbl using pspad to force the upload of the modded software. I've replaced these files in the iso using UltraIso. I've burned the new Iso image to a CD-ROM with no problems.

When I insert the disc into the computer, things progress normally, I get the message that software will be updated, the progress bar fills all the way up ....then I get a screen that says something about "errors encountered, please see user manual, eject disk and click ok". The nav goes to a black screen, until put the regular V32 disk in. The regular V32 disk installs normally and then system works fine.

Any thoughts on what I could be doing wrong when I create the modified V32 iso?

I recently found a copy of v27 so I tried the whole thing again by regressing to v27 and installing a modded v32. I replaced the sky and splash screen only....same "errors encountered" message.

Any pointers would be greatly appreciated!
