EkeEke c32af0586a [Core/SCD]
.fixed SEEK command emulation (Lunar the Silver Star freeze regression)
.added .OGG files support for CD audio tracks (use same naming convention as
.WAV files, cf. README.pdf)

[Win32]
removed win32/SDL port makefile to prevent stupid websites like EmuCR from
compiling & distributing it (for the last time, it's a buggy, unstable &
incomplete port which is not meant to be used for anything but debugging)
