Added zpu. Fix sdram 32-bit mode.
Added missing spi component! Fix pokey instantiation. Fix pause.
Connect up snoop to allow ZPU to see the data it requested
Always complete sram request if we have no sram
Moved ram complete back 1 Atari cycle - now runs fine at 4x speed. Some video glitches when running faster, need to investigate...
Fixed turbo
No need for mmu to deal with refresh at all
Cascaded pll in order to get exact SVIDEO frequencies
First cut with svideo, all versions from generic
Added os16_loop
First version that boots with sdram
Add an additional internal rom option - internal_rom=2, which for now just loops reading/writing 4 bytes. e.g. for testing new RAM setups
Final step of mcc216 build process - Windows only, appears to run in wine
svideo code provided by the mcc216 team
Re-connected SDRAM to DE1
Pass through video bigs
Build all targets...
Should never have been committed...
Use video bits generic
Added video bits to generic, since I am having to adjust this everywhere.
DE1 working with SRAM against common core. Plenty of features lost!
Adjusted this based on mist settings - in the hope this will mean I need to tweak the phase offset less...
Connected up SDRAM. Make 800XL core wait for SDRAM reset to complete. Also had to adjust phase offset to make it work - need to get a proper setup for mist
to_01 silenced sim, but caused build issues on Xilinx. If its invalid use 0
