All popular bank-switching schemes are supported including an extra 16K of RAM at 4000h.
Pokey support at 4000h, 800h and 450h - change this in Configuration if it's not auto-detected.
Starting with version 4.3, the new Banksets scheme is fully supported - this new banking/memory handling
is designed for homebrew authors to provide increased ROM density and improved packing and access
of graphics data vs code. This allows for games that would have been difficult or impossible without
the scheme. See http://7800.8bitdev.org/index.php/Bankset_Bankswitching for more details.

Add highscore.rom for 7800 High Score saving. This can be in /roms/bios, /data/bios
or in the same directory as the emulator. It's worth the effort to track down the highscore.rom file!

History :

V4.5b : 05-May-2024 by wavemotion-dave
V4.6 : 06-May-2024 by wavemotion-dave
* Each game that utilizes a High Score Cart (HSC) gets its own 2K .hsc file
* Improved High Score Cart (HSC) emulation - improved initialization of the SRAM contents.
* Sanity checks added so that carts marked as 'NORMAL' (or selected as such) but are larger than 48K will not corrupt memory.
* New magnifying glass icon to ZOOM (and center) the display 1:1 with real 7800 output. This will crop on a DS/DSi since it only has 256x192 but very useful to toggle the 1:1 zoom for High Score Entries, etc.
* Starting to lay groundwork support for .a78 V4 headers...
* Support for .a78 V4 headers (will fall back to V3 if not available)
V4.5 : 18-Nov-2022 by wavemotion-dave
* SNES2Atari adaptor supported.
