Rockman: Operate Shooting Star problem!

Ok, so i just downloaded a ton of stuff for OSS. I have No$GBA 2.6. I downloaded the pre-patched rom of OSS. also downloaded some firmware files and an IPS fix for OSS (Just in case). I extracted the OSS rom and tried to play, but i got this message right before getting to the title screen:
It wont let me get past that. Can't get to the main title screen or anything. Help?

Use 2.6a and a firmware.bin.
there's a full package here https://www.romulation.org/forum/index.php?topic=31241.0

I have firmware.bin already on mine. Whats the difference between 2.6 and 2.6a?

Many difference, it's highly suggested you use 2.6a
I can play the game using it. :)

Alright. Do all my saves on my other games stay if i use a different emulator? (Sorry, im new at this lol.)

If it's till no$gba you don't need to worry, changing from 2.6 to 2.6a can use the same save files :)

Ok i downloaded it. Although, its not recognizing any of my saves.edit: However, OSS is working on it now. :D

Do you use different folder for the 2.6a ?
Maybe you need to copy the save files, the save files are kept in the battery folder

Yeah i did. Where do i paste the save files for 2.6a?

If there isn't any, create a new BATTERY folder in the no$gba 2.6a folder and copy the save files there.

Ok its all working now. Thanks a bunch! :D

No problem :)
