Guys, could someone do an independent comparison of the speed of all the firmware versions on their systems, to see if there's actually a performance gain? I collected my own data using Dr.Hard.

At 1st we would need to download all 5 rom images somewhhere, I still have only 3. Btw your mod of 1ws stb rom was done on wrong offset so it cannot have any effect.

Yes, I saw your message. Unfortunately, I don’t have information about the correct offsets for those variables in the STB BIOS.
At the very least, please compare the performance of the original highspeed.rom file from GitHub with my version to confirm that the speed improvement is real and not just a result of some quirks in my hardware setup.

Yes, I need some time to find some free eprom/eeprom, erase it, pogramm... But I have some doubts as even in hispeed rom when disassembled there are no references to offsets you changed anywhere in code. So I would rather aim to reprogramm the mclk pll...
