WARNING! WARNING! WARNING!
The following text contains Spoilers! It is directed to the developer to inform him about something that seems to be a bug that is hopefully related to my hardware.
I am using an original DMG-Gameboy (1989 motherboard) with an EzFlash Jr. Cartridge (Firmware 4, Kernal 1.04e).
I breezed through this game in under an hour... More like 20 Minutes. First dungeon gave normal rewards. After that i ended with 99 Gold after completing a dungeon. After the third dungeon i had all items from the armory. I was so "lucky" that i just had to press rapidly a to get through all dungeons after the first. After the credits i got "back to town" and the lower part (where you would normally see "A=search B=leave" and stuff like that) was filled with garbage.
I can provide you with screenshots and a save data from the cartridge, if that helps.
My guess (and hope) is that it has something to do with the mapper that is used and that maybe a fix from your side is possible. I don't think the EzFlash-Team will release further updates :/
Nonetheless a great looking game! Sound/Music could have been better but for a GBS Title it is marvelous... Besides the musik ;) looking forward to future titles!
Keep up the great work!
