Did you really make this with QuickBasic?
From OHRRPGCE-Wiki
This article only applies to the DOS/QuickBasic version. It is not relevant for the current Windows and Linux versions
Yep. it's true-- For the first 7 years of its life, the OHRRPGCE was developed in QuickBasic 4.5, extended with an assembly-language library called Allmodex written by Brian Fisher.
If you are interested in learning Quickbasic, feel free to e-mail James, and he will talk you out of it. There are so many better languages you could learn :)
After the OHRRPGCE went open source in mid-2005, there was a concerted effort to port it to FreeBasic.
