Just a bit of info for anyone who had a similar problem. I had the could not open palette.bin error. Noticed that the data on mmc1 only totaled 6mb instead of 30mb. This was because the n800 uses it for virtual memory therefore hinders the installation. I removed virtual memory, formatted the card and reinstalled warzone 2100 and it works! Only shows about 27.7mb data on mmc1 but it works!
