Thank you so much for the detailed tests! It’s very interesting to know that speeder-kernels and cartridges like the AR6 or FC3 are working, even if the AR6 forces the text back to white.
Regarding the performance and the packing:
- Hardware context: I don't have the original disk drive hardware to perform real-world performance benchmarks. I usually conduct my tests using VICE (with true drive emulation) or on the MiSTerFPGA and C64 Ultimate.
- Compression choices: I used Pucrunch to pack the files to ensure everything fits on a single .D64 disk. I chose it mainly for compatibility, as I previously found that Exomizer caused some issues with the way I handle load chaining via BASIC.
- Next steps: Your suggestion about NuCrunch is excellent! If it provides a faster unpacking time while maintaining compatibility with my loading logic, it could be the perfect middle ground.
I will definitely run some tests with NuCrunch as soon as possible to compare the results. If it works without breaking the chain, it should significantly improve the experience for those using fastloaders where unpacking time becomes the main bottleneck.
Thanks again for the support and the invaluable technical tips!
