So I now how my new SDRAM card, and it seems to work - no errors to speak of on mem test after 5 mins... However, I am still getting just a plain grey screen whenever I try to run a NES ROM (from archive.org, nointo, full set); can anyone suggest a way forward please?

GBA game worked, for test purposes

Thank you

Thanks. Just so I am clear, it's a case of downloading a different archive, rather than using a program convert the ROMs?

if you have python 3 on your computer you can try to use this tool to convert your roms to nes 2.0 header. script requires New Rising Sun's NES header database for the link on the page.

This worked a treat, and saved me having to hunt for alternative files. Thank you!

Sorry, I have looked at the links provided, I can see how to switch into PAL, but I have no clue how to see a header 2?

Sorry to be a pain with all the questions - it trys to load to a grey screen and hangs.

Thanks

John

you cant switch it to header 2 in mister. you need a pc and then have python 3 installed on on the computer. then download the New Rising Sun's NES header database and put it in the same dir as the script and then put your Games there and then run the python script form the command prompt.
or you can find games that are already made too have header 2 on the internet.
