problem with snespowerpak and secret of evermore save

Post by renejr902 »

i have the snespowerpak since december 2009.

and i just discovered that YOU CANT save in secret of evermore.

because when you save the game, it will save but the file will be corrupt.
you cant load your game at all or load with a lot of glitchs. with any secret of evermore version i tried.
anyone can get the save working ?

thanks

I can confirm this issue. My ROM is a dump I made myself from the actual cart. Perhaps it's an anti-piracy measure or something.

Edit: Emulator saves load fine. Again, probably an anti-piracy measure, and in any case, it's probably going to require a patched ROM (as with Star Ocean). :(

Secret of Evermore isn't known to use any form of anti-piracy. Atleast UCON64 doesn't crack it and it cracks most if not all SRAM based anti piracy as well as a few of the Capcom ROM based ones.

Do you have to go far into the game to save? If I have time I'll try it out. I can't think of any good reason why it wouldn't work properly unless it is detecting header information wrong.

Sounds to me like a software (read: 65816 code in the ROM/game itself) checksum problem of some sort -- lots of games can suffer from this issue.

There is no evidence to suggest it's an anti-piracy effort, so that should be considered complete FUD at this point in time. Please don't go that route.

I stand corrected on the cause (which was just a guess anyway).

As for how far you have to go to save... I'd say it takes 5-10 minutes on a totally fresh file. However, if you have an existing save and start a new game, you can hit Start to skip the initial cutscenes, then head up, avoiding most of the plants' attacks, then die at the boss on the next screen, at which point you will be dragged to a save point where you can save in another slot.

From there, a soft reset is enough to see that the save in the new slot is corrupted.

My tototek flash cart should arrive shortly and I will be sure to test it out when it does. Then we will have more info on where this behavior come from and if it's something caused by powerpak itself or something else.
