Some WIP news:

A new version of the rombank program will be released soon that I hope will resolve all remaining issues people have had using it to create ISOs. In the mean time, I am continuing to work on getting memory card compatibility up. I will need to purchase memory cards for testing so please email me or post in the forum which brand/model cards currently do NOT work with imbNES. Also, I have set up a paypal account to accept donations to help cover the cost of memory cards, a multi-tap, a light gun, new PSX dev equipment and anything else I’ll need to buy to further develop imbNES. If you would like to support this project, feel free to make a contribution. Contributors will be recognized in the program and held in high regard by all!
