I ran the installation with the new instructions and it still fails. I've tried both the standard install process as well as the quick installation. Each time I used a clean install of RetroPie 4.4

@meleu I have a more generic plan for modules, but needs some more planning and work. Es-dev was a quick fix due to breakage, but I'd rather not do more.

@pjft you're my hero! I'll try that when I get home and update this if it's solved or not. Thanks, man!

I'm curious as to your thoughts on this idea. The existing version of dosbox is very good. It has speed and compatibility with most every dos based game. At the experimental end of the dosbox spectrum for PC, people created branches like hal9000 or daum or dosbox-x to do opengl, advanced hardware emulation and the ability to create some pretty gnarly situations (like early 2000's windows game support). The issue with the experimental builds is that while they can do incredible things with newer games, their compatibility with old games is sometimes a little suspect.

What if you treat the experimental versions of dosbox like experimental packages and housed them like separate emulators? Most of them have source code packages that can be compiled for pi. I'm just curious to your thoughts on this as an eventual direction you may decide to go in.
