: : : neogeo emu , as i said before is gonna be tricky,
: : : as we have not enough ram in the DC to fit the ROM

: : Well, another thing you can do other than read in parts of the rom would be to try to use memory mapped files.. what this means is windows (ce or 9x/nt) opens a file handle and then gives you a memory pointer to the file's beginning.. then you can access the file via memcpy etc...

: : Atani

: Hy, thanks for you thoughts,
: but to me what you are talking about has the
: same slow speed as memory paging, or am I missing
: something? (in the end, you will have to access
: stuff which SHOULD be in RAM from the CD, which
: is roughly 1000 times if not much more slower.)

The CD may be slower (probably is) but with using the memory mapped files system you dont have to write any extra code. It is completely transparent to the program that is running.. Also, how much free memory do you have at runtime?
