if it was possible to modify a spectrum emualtor so that it loaded 48 programs - we are still only allowed to use 48 stuff?
couldnt it shove hmpr block C&D in external ram
wouldnt vector stuff be the best place to start seeing as it takes more than one frame to draw so any timing increase might be handled automitcally by the external ram rather than sprite scrolling glitches?
naturally any 128 paging will crash ditto ay8912 128-fuller/dktronics/cheetah wont be converted either

was hoping emulator explosion which does detet external might be able to use but have emailed velesoft a couple of times asking and so far no joy

no one like the hi deff ati animation then? - i know too many social net invites….

right at the end two discs set external 1-4mb sim coupe then option two on menu should work with most 48 SNA not 128 or multiface or .kul
someone seems to be converting speccy stuff for ay interface
can these be converted to sam? also a mouse interface - sam mouse?

using comet assembler?
how do you compile it to external 1mb?
how do you bank switch so you only need to use two routines to copy 8kb a piece and use the bank switch to copy the same area to a different location?
ld sp,nn
pop af bc de hl
exx ex af’
pop af bc de hl
ld sp,nn
push hl de bc af
exx ex af’
push hl de bc af

204 tstates 16 bytes shuftied?
24576 bytes for mode 3/4
= 313,344 tstates for full screen from ram to ram so no use for reading a port for atom lite which is at least 16 tstates per byte so a further
393,216 tstates
but a lot less with a DMA

there’s a line interrupt there anyone manage to alter it so that two line interrupts are used to turnt eh screen on and off for mode one might save the asic waits in the border?
line 0 screen mode 1 vmpr and border port screen on
line 191 screen mode 3 vmpr then border port screen off - or if it was 3d vector /freescape turn it off immediately after the viewing windows last line and on again just before? do i need to explain?!

Speccy 128k conversions on Sam

Submitted by Simone Voltolini on Thu, 2014-08-28 20:08.

I Would like to know how Many 128k games were converted to the Sam.

I’ve found online 30 disks and I’m on the way to convert Many Of My Speccy games that I’ve crunched AND restored so well on The Speccy.
