vecx-sdl2's Issues

include file syntax, and 48k or 50k cartridges

#include "emu\e6522.h"
#include "emu\e6809.h"
#include "emu\e8910.h"
#include "emu\edac.h"
#include "emu\vecx.h"

using backslash only works on windows systems, but using forward slash will work on both windows and linux systems.

Also, in vecx.c the cartridge size is limited to 32K but Vectrex cartridges can in theory support up to 50K as the address space for cartridges runs from 0000 to c7ff, and some cartridges are beginning to use that extended space.

< else if (address < 0xc800) /* WAS 8000 - updated for 50K carts */

  else if (address < 0x8000)

< else if (address < 0xc800) /* was 8000 - updated for 50k carts */

  else if (address < 0x8000)

the declaration of the cartridge space should also be sized appropriately. Although you are more likely to find cartridges supporting up to c000 (48k) than c800 (50k). This is regular non-bank-switched memory. Bank-switch support is a separate issue.
