this is the nicest I've ever seen gbatemp act to someone who necro'd a thread that's been dead for near a decade.
I kinda dig it tbh
Most such things tend to be someone necroing to say +1 or "I agree" which is fairly pointless. Someone wanting a fix that still works (not like the games change) might be pointless for me (again pocketnes and HVCA offer superior experiences) but easy enough, even though as noted my link in the last post still works.
Are these patches batteryless?
I am not sure what that means in this context.
Batteries exist for two, maybe three reasons in GB/GBC/GBA games
1) To power the real time clock.
2) To power the SRAM.
3) To power rumble in some specific instances, mostly a handful of third party rumble and GB/GBC stuff*
No classic NES/famicom mini (or NES as far as I am aware) effort ever had a real time clock.
There is some discussion in game collecting circles wherein later reruns of GBA games moved from the classic battery backed SRAM to what was then shiny and modern FeRAM/FRAM that functions much the same (it is often literally the same ROM when dumped and the save code is contained within ROMs on the GBA, hence patching them for older flash carts) though not needing a battery. All these that had saves (some NES games have no save and correspondingly these emulated versions don't, don't think any magically gained previously lost code**) are various flavours of EEPROM and thus does not apply either.

**occasionally to get it out cheap then the dev/pub would drop normal saving games to password mode, the coding tending to be left in so hackers could patch it back in, or they would do it themselves.
