Thanks for informing,
If the wireless adapter plugs into the USB port, then it only works on PS2-Linux 2.6, which still needs a few drivers to work like PS2-Linux based on kernel version 2.4. The USB port is very slow compared to the ethernet port. If the gaming adapter plugs into the ethernet port and then transmits wirelessly to your router, then it is functioning as a bridge. Bridging is known to work, but without knowing the make of the gaming adapter, I don't know if it has this function.
I think every thing including windowmaker, abiword, vnc etc are there in the blackrhino rte cd. but the installer has only the function of intalling it into the internal hdd, could you make (after you are free) an image of it for the ps2 slim, a usb image that is, also is ps2 70004 v12? if so it wouldn't have any problem with the usb wont it? except the fact that it'll be slow. And can fire fox use the adobe flash player? if not, i don't mind not having it. Also, can dillo browser download files over internet like a normal computer to the flash drive?
At the moment, I'm too busy with my other commitments to spin off an updated version of Mega Man's excellent LiveDVD version 2, although I'm sure there are a few programs most people would like. Sorry. While I was tremendously disappointed with Firefox performance on PS2-Linux, I realize others might disagree. Since you have a Slim, your swap storage would be over the network (or maybe worse, usb). I was disappointed with performance with a FAT PS2 and a hard drive for swap, so without a hard drive it would be significantly slower for most web browsing. Maybe others on the forums had a better experience, but it was so bad for me (multiple versions, multiple attempts) that I decided not to include it on my distribution.
