Hi Rob,
The GameBase tool was made way back in time using Visual Basic 6.
James (Jimbo) Burrows did tinker with a completly NEW engine using SQL.
however this project was never finished due to family and work commitments.
I have tried many frontends over the years, and always comeback to GameBase.
Even though it does have many flaws and bugs.
The easy of use and very small footprint (no bloated nonsense) makes it a winner.
A programmer has long been needed to update /convert the GB code to VBNET ,C++ or something that can be compiled to many platforms like MAME.
The original source code is freely available as a starting point.
But i fear it would need a complete rewrite for mac OS compatibility.
There is a JAVA version of GB which is supposed to work on MAC?
https://jgamebase.sourceforge.io/
but the MDB code needs to be converted to use that format and folder structure.
I am, you are, we are, they're not...
