Relics: Ankoku Yousai for FDS from Project EGG

[f-fix]

The loading times in this game are pretty awful and it happens frequently, so I understand why EGG used a modified BIOS and emulator to speed those up. I know this game gets a lot of flak, but it really does have some interesting-for-then mechanics and some of the music is decent too IMO.
I was able to extract a disk image from a Windows process memory snapshot of the freely downloadable (no subscription required) Project EGG version of ボーステック/Bothtec's RELICS / レリクス暗黒要塞 (Relics: Ankoku Yousai, i.e. "Relics: Dark Fortress") for the Famicom Disk System, only this version was modified to remove the license file and disk header needed to run with the normal FDS BIOS, and also had two changed instructions that caused it to crash when run with the normal BIOS once the license file was restored. I made a patched version that fixes these problems so it can be played using a normal BIOS. Note that unlike the version previously released on physical FDS disks, this one has all user instructions regarding disk changing removed - you will need to intuit when to flip the disk over, or notice the briefly displayed letter A or B on the screen.
