@retropieuser555 You can safely assume that any game listed on GOG is x86 only.

If the game's engine is open sourced (like Doom3, Quake series, some Tycoon games, VVVVVV,etc.), then it's possible to re-use the game's assets (which are not open sourced) under a native (ARM) source port. If it's a DOS game, then it will run under Dosbox, but if it's Windows only and there's no native ARM port, it's always be an x86-only affair.

@mitu I see what you mean, thanks!

Hello folks,

Sorry if this is old news, but did you know you could build Alien Vs Predator Classic (the Rebellion game from 98) on a pi?

The source is here: http://icculus.org/avp/

@shavecat Captain Claw can be done, you just have to do it your self, but there site

https://github.com/pjasicek/OpenClaw
if you feel comfortable with doing it

ExarKunIv

@mechafatnick thanks for that, im so going to give that a try

So gents

since i was able to be blood running i wanted to try my hand on a few others. so i decided on Dune legacy. since it we talked about it ealery on this post.

i was able to get it co compile just fine. and if i exit ES and run ./dunelegacy from the dunelegacy dir. the game launches and works just fine.

but i cant for the life of me get a .sh file to get it to launch.
looking at the runcommand.log show that it is starting fine and no errors from there.

my dunelegacy.sh

#!/bin/bash
"/opt/retropie/supplementary/runcommand/runcommand.sh" 0 _PORT_ "dunelegacy" ""

my emulators.cfg in /opt/retropie/configs/ports/dunelegacy

dunelegacy = "/home/pi/dunelegacy/dunelegacy"
default = "dunelegacy"

want am i doing wrong. im so confused since i was able to get Blood to start from ES with out a problem

@ExarKunIv

dunelegacy = "/home/pi/dunelegacy/dunelegacy"

this doesnt seem right, where is the dunelegacy file extension? is it an .so? an .sh?

ExarKunIv

@quicksilver i dont know. there is no extension.
it is just a file. but as i said if run ./dunelegacy from the dunelegacy dir the game will start.

i did get a shell script before that installed it all for me, but that version the screen flickered. and that was also on a old build that i lost sometime ago
i did find some files from that build and they where calling on a .sh.
but i dont know what was in it

this is a old issue that i found on github. that im looking at for pointers
https://github.com/zerojay/RetroPie-Extra/issues/264

but no luck yet

@ExarKun I've have had similar issues before where a port I compiled, I can run from command line but when I try to get it to run through runcommand it won't work. Hopefully someone who knows more can chime in.

@mechafatnick I can provide a script for you that I have created a long time ago if I can find it. The script is used to automatically compile and build a working Alien Vs Predator Classic binary as it only works in X11 environment. You will need to run the script and the game from the Raspbian Desktop. Notice that the gameplay is really slow. It is almost unplayable on a Pi 3B.

@ExarKunIv Maybe it has something to do with the working directory. If you execute ./dunelegacy you are already in the /home/pi/dunelegacy/ directory. When you start the game with runcommand you (maybe? probably?) are not. Have you tried copying your game files to /home/pi/.config/dunelegacy/data/ as it is suggested in the dunelegay manual page?

IIRC that's also what the -j=/home/pi/RetroPie/roms/ports/nblood command is used for for nblood: It sets the search path for the game content. Maybe something similar works for dunelegay? There should be a config file, maybe look there?

ExarKunIv

i did get it to work.

i just made two .sh files. one for the run command and the other to start the game, that is called by the runcommand
might not be the best way to do it, but it does work and my BGM turns off.

so ill take it as a win

but theres no mouse pointer, lol.
least learning how to compile and get games working is fun. :D

mechafatnick

@tpo1990 Thank you! That's a bit of a shame! :)

retropi19

tpo1990 can you make a script for the nblood engine? to compile and install ?
also a script for alien vs predator would be welcome

quicksilver

@retropi19 for AVP check out this thread https://www.raspberrypi.org/forums/viewtopic.php?f=78&t=100152

Looks like someone put together a bash script to install it.

i was able to get Rigel Engine to compile but then i get a
ERROR: SDL error: Could not create GLES window surface

im going to guess we need a desktop for this one to work, but i did have fun learning how to get it to compile.

and i did get Captain Claw to compile and play.

i think it was a bad idea for me to start messing with compiling games. now i will never play anything. to busy trying to make games run. lol

This is exactly my problem, getting game engines to run on the pi is just as much fun as playing the games. Though I am over half way through half-life now. I forgot how good that game is.

I see people have gotten doom 3 running on the raspberry pi, that might be the next thing I try.

i saw that too, but i thought that one might be like OpenJK where is need x11 or whatever the desktop is called. so i decided not to bother and wait for someone who is not like a week into compiling to give it a try. lol

Got dhewm3 (doom 3) compiled. It actually was very straight forward. Performance is fair, video quality has to be reduced to low and game played at 640x480 in order for the framerate to be playable.

Game runs much smoother in an x window and the main menu isnt glitched. I just cant figure out how to use the startx command through runcommand. It always fails.

ExarKunIv

@ecto so my system that i was compileing on went bad.
so i decided to try 4.6. now i cant get Redneck Rampage, Blood, or Exhumed to compile.

i get getting a

source/build/include/build.h:615:20: note: code may be misoptimized unless -fno-strict-aliasing is used
/usr/bin/ld: /tmp/cc1om8Ed.ltrans11.ltrans.o: in function `enet_time_get':

/usr/bin/ld: <artificial>:(.text+0xd28): undefined reference to `__atomic_compare_exchange_8'
collect2: error: ld returned 1 exit status

the only thing i was able to find online was this

Change CMAKE_CXX_FLAGS variable in CMakeLists.txt file (in the main directory). i.e. add line set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -latomic")

but there is no CmakeLists.txt in NBlood.

im so lost on this one,

any thoughts.
yes i did post it on the GitHub for NBlood
