2017-01-22Force IPV4 for GDB remote debugging on Windows. Bind to localhost instead of ↵Michael Pavone
unspecified address since listening on external ports probably isn't a good idea in the general case
2017-01-19Fix border rendering at end of line 1FE. vdp_inactive will probably need a ↵Michael Pavone
small fixup for the edge case when we start between when the vcounter is incremented and the line is truly finished.

2017-01-15Don't adjust cycles every frame. Only when we start getting close to ↵Michael Pavone

2016-12-27Somewhat broken implementation of Mode 4Michael Pavone

useful.
2016-12-12Fix field flag handling bug introduced with VDP/render interface cleanupMichael Pavone
2016-12-09WIP split of ROM loading/argument parsing from Genesis emulation code. ↵Michael Pavone
