OK - what you posted is "the usual" result from XIPPorterEx with the remove CacheFilt.dll and remove Mencfilt.dll checkbox enabled, plus the other usual modules removed. No other changes. In other words, it's a slightly size-reduced XIP but no tweaks. If the ONLY difference between a working ROM for you and non-working is this, then there is obviously some dependency.

I haven't cooked with 21028 yet. lllboredlll has and unless he hasn't bothered to report it, I don't think he's had the problem you are having. Which implies that the dependency could also involve the SYS build plus the XIP.

So anyone that's used this XIP - please report a) what SYS you cooked with (version AND source) and b) if it's working fine or if you are seeing strange issues.

I made exactly the same changes to 20771 and have been running for a week now with zero strangeness, nothing wierd.

One more question - are you using the default .VM and .SYS, or are you using the modified ones I included in the XIP .ZIP file? Where in the build process do you do G'Reloc.exe and what exactly is the command line? Have you dumped your ROM and looked at the virtual memory map (imgfstodump.exe creates memorymap.txt - can be useful to see if there is an overlap in any of your modules with the XIP module VM space. Just another thought. This feels like a filesystem bug though...
