I was more than happy when I saw a thread about this translation on Sega-16... However, I've tried to run it on my Japanese Mega Drive model 1 using an Everdrive MD and then I got nothing...
I thought the password system was not working (according to the translation patch page) but later I realized that you just dropped the Japanese system, so no problem at all about that IMO.
But, if you could fix the instructions that make the game crashes on real hardware, I would thank you for the rest of my life.
I think the hardest part of the job you have already done, so I just wish that you can have enough time/resources to fix it...
Anyway, I just wanna say THANK YOU for picking such an obscure (and great) game and making this GREAT effort.
The script (on emulation) is perfect AFAIK.
If you need any help about testing it on real hardware, please, just let me know.
