|Summary||07435: Vector: Vector Many games do not return stably from save state|
On my machine, certain vector games no longer return stable from their save state. I have tested this using autosave = 1.
From 0.210 forward, the graphics on a return to state are glitchy, or missing entirely. I have noticed this in Tempest, Omega Race, Asteroids, and Major Havoc. There may be more. Asteroids Deluxe and Battle Zone appear to work properly.
From 0.209 back, the screen graphics show up as they were when the sta was taken in the problem games.
|Steps To Reproduce||
Set autosave=1. Launch affected vector game, either with HLSL or without. Exit emulator. Relaunch vector game restoring from the autosave.
Graphics are glitchy. They disappear entirely, or random lines appear.
Launch 0.209, set the autosave=1, launch and relaunch, graphics appear as they were when the sta file was taken.

Doing some save state testing I can confirm I see multiple drivers which now do not restore 100% properly anymore. Have traced breakage to this commit:

It's a problem due to the use of the required_shared_ptr for vectorram instead of the pointer. It somehow messes up savestates, probably because of the mixture between ram and rom memory entries in the drivers.
I think it'll be fixed when OG's next memory update will be merged.
