New in this version:
– The project is now named bsnes-hd as HD Mode 7 mod was simply
too long. Also I have moved beyond just Mode 7 and have plans for more. A
repository will be available soon.
– Widescreen for non-Mode 7 backgrounds. Results of course vary between
games and even scenes.
To avoid HUDs repeating and other unwanted effects I have added settings to
disable widescreen for the separate background layers and even just the top
or bottom of a layer.
The default is always on for all 4. Sample values for some games are:
F-Zero BG3: off HyperZone BG2: >80 Please post settings for other games here.
– Sprites that are partially inside the non-widescreen area are now drawn
entirely when possible.
The new unsafe sprites settings allow sprites to enter widescreen areas
further if the game keeps updating them. This will however cause significant
artifacts in many games. If ROM-hackers want to discuss optimizing games for
this, feel free to contact me.
– more widescreen aspect ratios (16:10, 21:9, …)
