Mesen core and SRAM

[televandalist]

Due to how many achievements do not work properly in both Radia Senki and EarthBound Zero using Mesen, I decided to look further into it. It definitely seems tied to SRAM, at least.

The following games have sets on RA and have code notes within SRAM: -Chronicle of the Radia War | Radia Senki -Destiny of an Emperor -Digital Devil Story: Megami Tensei II -Downtown Special: Kunio-kun no Jidaigeki da yo Zenin Shugo! -Dragon Warrior -Dragon Warrior II -Dragon Warrior III -Dragon Warrior IV -Earthbound Zero -Final Fantasy -Final Fantasy II -Final Fantasy III -Kirby's Adventure -Legend of Zelda -Maniac Mansion -StarTropics -Sweet Home -Zelda II

Several of these games have tickets, some for cheevos that utilize SRAM, some don't.

These are all tickets opened on 'SRAM cheevos' by users playing with the Mesen core: https://retroachievements.org/ticketmanager.php?i=16432 https://retroachievements.org/ticketmanager.php?i=16377 https://retroachievements.org/ticketmanager.php?i=16374 https://retroachievements.org/ticketmanager.php?i=16373 https://retroachievements.org/ticketmanager.php?i=16372 https://retroachievements.org/ticketmanager.php?i=15881 https://retroachievements.org/ticketmanager.php?i=18783 https://retroachievements.org/ticketmanager.php?i=18780 https://retroachievements.org/ticketmanager.php?i=18134

I did the same thing for GameBoy/GameBoy Color, too. All SRAM related:

I tested this one and could not reproduce the issue. Considering all the reports for this title are from the same person I am not convinced that the issue exists to this day, and if we want to have any hope of fixing it a reliable sample is needed anyway (e.g. save state before a trigger that should unlock but does not).

This is more easily reproducible with https://github.com/meleu/RetroArch-problematic-cheevos/issues/42.
