Title: emulation on linux 64 bits
Post by: philippe.ventrillon on April 03, 2016, 03:28:56 PM
Hello,

I had some troubles getting a working videopac/odyssey 2 emulator on Ubuntu 15.10 64bits.

Here is how I succedded http://emulvideopac.blogspot.fr/2016/04/64bits-linux-and-odyssey-2-emulation.html (http://emulvideopac.blogspot.fr/2016/04/64bits-linux-and-odyssey-2-emulation.html).

The blog is also available in french http://emulvideopac.blogspot.fr/2016/03/linux-64-bits-et-emulation-videopac.html (http://emulvideopac.blogspot.fr/2016/03/linux-64-bits-et-emulation-videopac.html)

I used Montjoie's o2em2 and I say "thank you" to him for this o2em fork.

Hello Philippe,

I succeed compilingo2em118src on ubuntu 14.04 64 bits. I add no problem except a missing include file in score.c (like you did in your old post I found later ...).
The problems I had was:
- incomplete/incorrect documentation about roms and bios path arguments
- total mess with bios CRC check: I finally force the  o2flag to 1 in identify_bios()
After that, I was able to start it and play the "Glouton et voraces" (K.C. Munchkin!) game.

I am not sure to understand the problem you add with allegro: when I check the allegro installed version, it looks to be  liballeg.so.4.4.2 on ubuntu 14.4 too:

$ find /usr/lib -name *alleg*
/usr/lib/x86_64-linux-gnu/allegro
/usr/lib/x86_64-linux-gnu/allegro/4.4.2/alleg-alsadigi.so
/usr/lib/x86_64-linux-gnu/allegro/4.4.2/alleg-alsamidi.so
/usr/lib/x86_64-linux-gnu/allegro/4.4.2/alleg-dga2.so
/usr/lib/x86_64-linux-gnu/libjpgalleg.so.4.4
/usr/lib/x86_64-linux-gnu/liballeg.so.4.4.2
/usr/lib/x86_64-linux-gnu/liballeg.so
/usr/lib/x86_64-linux-gnu/libjpgalleg.so.4.4.2
/usr/lib/x86_64-linux-gnu/liballeg.so.4.4
/usr/lib/x86_64-linux-gnu/pkgconfig/allegro.pc
