Also I have firmware 1.04 which from what I have read is not what anyone is working on so I guess I'll be the first. If I could make a comment to all the beta testers and well wishers out there, just as an outsider, maybe you should post which rom your running so developers can know what is most requested.
What is "most requested" is not the point. If you are the developer, and you have a G10 with FW 1.04, then you can only develop&test a port for the 1.04 fw. Other fw-version ports are (usually) different and wont even start on your G10 with 1.04 fw. So you cant boot it and not test it on your camera. So as a developer, as first step you have to get the port running for your specific camera/fw version. If this is done and everything is working, it is possible to adapt the (running&tested) port for other fw-versions. Trying to create a port from scratch for a camera/fw-version you do not have is really quite a challenge...
So first you have to get a port running for one firmware version. If there are more fw-versions out there, the port must be adapted. For adaption/porting a firmware dump is necessary. So if you have a "new" fw-version, you can try to make a fw-dump of your 1.04 firmware, becauses this is needed for a 1.04 port anyway.
