Hi Xang
TOSEC wasn't "desactivated"
it was/is just much slower / stopped due to interest and contact between members (...), the iso part was still working and well maintained over toseciso.org.
We are trying to bring back the project activity and do some great work, for now not by adding tons of new stuff (wrongly and full of errors like before), but fixing current bugs and doing small, correct additions.
As for your tool, i've downloaded and launched it, it uses some kind of db and remembers me some kind of TIM or tugid style, i can't test it much because i'm busy with other things currently and have lot to do (+ don't have much sets left to test).
Most of the people i know just uses clrmame to manage their roms but i bet there are others that may like your tool and if it is useful and serves your needs i think it is good, interest in tosec is always great and i like having that kind of surprises.
Thats all for now, thanks for your interest too in our project
Stay around, there might be more news one day, just hope it doesn't take years again
