that screenshot was from Gens.. I was trying to post screenshots of Sonic CD running on AGes but the pics don't show up.. Only a large square with a little square at the top left.. weird.. Maybe its the way Ages makes the screenshots..
I recommend you getting Hypersnap DX, and configure it to autosave... I have the program, and use it for all my screen captures. I don't have to leave the game to save it so I don't lose it... I configured it to auto-save. I highly recommend this tool.
ahhh.. Gotta love them loops.. They get even more crazy later on in the game.. Did I mention the music is also pretty cool.. Plus being on CD helps a lot with music and sound effects.. Crystal clear.. As with all Sega CD games I have tested..
I am pretty impressed by the level of sega cd emulation.. It can only get better people.. Just have to play LUnar 2 again.. I got the game but it doesn't work well yet on any of the current versions of sega cd emus.. But the future looks very bright..
