I have the Neo2Pro, 1024M ROM, 256 RAM, 16M Menu, 2M Save, with SD Card slot. I finally got it to format which takes about 3 hours. I am using the newest Pro Programmer V1.2, newest Super MD plugins, and Neo Myth Menu DX. I copied the plugins in the plugin folder and the menu where the bios are as I read. It has the newer menu where it has the fancier fonts and everything is arranged alphabetically. Now the cart with the SD card can read the ROMS off the SD card no problem all though it is very slow. I imagine since it has to read through the SD card, burn to the Cart, and then output to the sega. That works fine, but I cannot put any ROMS on the ROM cart itself. In other words I want to put the bigger ROMS on the 1024M cart and leave the rest on the SD. I hope I am explaining this right. The cart not only has a SD slot but 1024M of ROM. Also I read here it reads all ROMs regardless of region. However I put a PAL in and it says its for PAL only. Am I suppose to do something to make it work? I go into options and its only for saving, which also seems to work fine. The cart does not read any Sega MAster System ROMS. Now I know my master system ROMS are good because I also have the regular 1024M card WITHOUT the SD port. When I format this specific cart, it comes back calculating all the bad blocks and I am left with 502 megabits. I have to use the older software to upload sega master system ROMS only into that cart without the SD slot. However the old software does not have the cooler menu and games are arranged not in alphabetical order but rather how I burned them. For the life of me I cannot get RYGAR to run in SMS. I have downloaded every rom and that one never works. I remember it working before when I first got this cart 2 years ago. Maybe as the menu and programmer keep updating it becomes less compatible. Anyways, I am sorry I sounded like a dickhead. I was just mad.
