I don't get it....how and from where do I flash this cartridge?
Assuming you mean the The!cart.....
Well... I was about to say "oh that's easy" but then I went and try to look into it and.....it's not _that_ easy, at least....well...
OK this is what I understand: you use the Studio software on your Mac, Linux machine or PC to create the flash file. Then you either need a SIO2PC connection (that means one of those SIO2USB or SIO2PC interfaces, or like I did, solder one simple chip inside your A8 machine and hook it to a standard RS-232 connector)) OR you need a SIO2SD "drive" to get the data across on the A8 and into the cartridge.
I think this is the bottleneck of the system. Not everyone has a SIO2PC connection on their A8 and if you already have SIO2SD why bother getting this cartridge ?
I asked this on the Atari age thread. A "competing" sytem from Atarimax uses a dedicated cable to program the flash cartridges directly from a PC. However these cartridges are 8Mb max which would really make you need quite a number of cartridges to get a reasonable amount of games, and that is expensive and also a lot of hassle.
If/when I understand the entire process I could fill one of those The!carts for you Thorsten because I already have one A8 machine with SIO2PC conenction. Let's see the answers on Atariage......
