converted namcos1 to use delegates instead of _space_func and modernized all remaining functions (nw)
fixed silly mistake with 32x hi-priority pixels. nw.
stop SMS VDP timers in systems that don't need them. nw.
doing a check if read is safe, but think this need more investigation, why it was called by acia (nw)
hsync and fsync are part of mc6847 so devcb2 conversion was needed there not in gime, this fixes coco3 issue (nw)
change sega genesis vdp to use macros instead of direct usage of callback defines (nw)
replaced some malloc/free usage with global_alloc_array/global_free_array (nw)
replaced some more malloc/free usage with global_alloc_array/global_free_array (nw)
(MESS) pet_rom.xml: Fixed validation. (nw)
converted some global_alloc_array() usage to dynamic_array/dynamic_buffer (nw)
namcos23: Get some speed back (nw)
Need more sleep.  Or beer.  Or something. (nw)
actually mark as not working until shoutime finds time to dump the rest of it (nw)
Definitively more beer -- fixes invqix at least (nw)
4enlinea: Hooked a status handler for the HCGA controller.
(for now, simulating the state). Improved the memory map
fixing the RAM amount and offset, and added the correct
offset for the HCGA status. Also hooked 2 debug handlers
on ports e000-e001 that spit some random graphics after
30 seconds of the game execution (clue to figure out).

improve 4enlinea video rendering a little (nw)
- BetaDisk fixed (there was just needed to start floppy motor ;) [MetalliC]
- Pentagon: fixed 7FFD port addressing; CPU clock fixed; adjusted VBLANK
IRQ timing (border effects works fine now);
- Scorpion: fixed ports addressing;
both machines marked as working.
Notes:
- there are still issues with BetaDisk - for unk reason wrong commands
passed  to WD17xx (imho ROM switching works somehow wrong), but anyway
with  write protected disk images it works more-less fine - files from
disks loaded OK;
- Pentagon1024 randomly crashes then selecting "GLUK BOOT", maybe
also coz of rom switching.
another small step towards separation of the 32x from megadrive vdp. nw.
s3: fixed typo (no whatsnew)
rm leftovers
