i actually have the same problem...err sort off
i acquired the PSX of WC3 Heart of The Tiger of Ebay and played it on me ps2. I got a ps1 memory card, insert it and it doesnt save...the ps1 memory card is dodgy to the game, here's the PROBLEMS that i have laid out in simple points:
*note - the ps2 does detect the ps1 memory card
- First time playing the game...i woz asked to format it...i did...saved it.....switched it off...then when i played it again - next time round - the wc3 save files were gone...no where to be seen in the duty roster.
- One time i played it again, saved it. Took the memory card out, switched the ps2off. Next time i inserted the memory card to play the game although b4 inserting the game, i went into the browser checked the data of the memory card and the wc3 save data woz there. But then i inserted the game in checked the duty roster and nothing WOZ THERE!?!? scrolled up and down...NOTHING!
Any help...it maybe complicated but i jus cant load of the game from where i finished meaning everytime i play it i always have to start at the beginning.
