V5.6a : 08-Oct-2024 by wavemotion-dave
* Fix to allow JLP games to execute out of 16-bit RAM. Fixes Defender of the Crown.
* Improved UI display of 'JLP FLASH' so it shows a bit longer (but doesn't interfere with emulation speed)
* Numerous new overlays added.
V5.6 : 06-Oct-2024 by wavemotion-dave
* Massive overhaul to the way overlays are found and loaded. No longer do you need to have the overlays named the same as the game ROM file - the emulator should find the matching overlay 99% of the time (and yes, you can still force the issue by naming the .ovl the same as the base game .int/.bin/.rom file)
* If the system BIOS files are not found by name, a quick search is done by CRC32 to see if the emulator can load it.
