Installing .Deb or locally saved Package

Im trying to install Previous the Next Emulator.

From the website I downloaded the .deb file, then used debtap to convert it to a arch package, but I have no idea how to install this.

Ive also tried using paru to install previous-svn but get this error message

'/home/sneeker/.cache/paru/clone/previous-svn/src/previous/src/ioMemTabTurbo.c:236:17: note: (near initialization for ‘IoMemTable_Turbo[143].SpanInBytes’)
make[2]: *** [src/CMakeFiles/previous.dir/build.make:331: src/CMakeFiles/previous.dir/ioMemTabTurbo.c.o] Error 1
make[1]: *** [CMakeFiles/Makefile2:367: src/CMakeFiles/previous.dir/all] Error 2
make: *** [Makefile:136: all] Error 2
==> ERROR: A failure occurred in build().

error: failed to build 'previous-svn-r1466-1':  
error: packages failed to build: previous-svn-r1466-1'

Any ideas on how to get previous running under Cachy?
