Unable to play Minecraft on lower end G4’s or G3’s? There’s a solution to that! Enter ClassiCube: a continuation of Minecraft Classic written in C. Relatively recently I had the opportunity to get it compatible with G3’s through persistence. It runs with about 20 FPS on a 500 MHz G3! https://home.macintosh.garden/~retroreviewyt/classicube-ppc.html

Hey this is pretty cool! Thanks for getting something like this working on 10.4 and the G3 systems. Although if anyone wants a Leopard specific newest version of ClassiCube, I uploaded a compiled binary in another thread on this forum. Here's the link:

Minecraft Classic for Leopard PowerPC

It does run a little worse I think, but I just though I'd mention it.
 
Oh wow this is great. I haven't played ClassiCube in ages but I was very active around the time it launched almost a decade ago.

Happy to say it works great on my 2005 PowerBook G4 12". Getting a stable 35-50 FPS on a 128x128 world.
 
It would be cool if the multiplayer worked though. It keeps complaining about CA certificates. I know you can get more up-to-date ones through MacPorts, but I don't know how to use them with ClassiCube.

It should work for local multiplayer games.

I think that’s a problem with Tiger? I’m not entirely sure though. Might be fixable by installing TenFourKit’s certificates.
 
No, multiplayer doesn't work on my Leopard build either, so its not just Tiger. I know that there are ways to "relink" some apps with newer CA certificates like in this post:

Playing YouTube via VLC

To play YouTube through VLC you need 1. Install: VLC 2.0.1 (In folder Applications -> "/Applications/VLC.app") MacPorts 2. Install curl-ca-bundle through MacPorts sudo port install curl-ca-bundle 3. Add new SSL certs to VLC mkdir -p ~/Library/Preferences/org.videolan.vlc/ssl/certs ln -s...

I just don't know how you would do that with ClassiCube, and you also need MacPorts to actually get those certificates so that would be inconvenient for most people.

Might be wise to try compiling the latest version of the source? I compiled this when the developer added the ability to compile natively under Tiger. It originally required Leopard to build for Tiger.

Try compiling my copy of the source located on my GitHub repository. I added a particular line to the network stack the application uses that’ll hopefully fix the problem.

This is awesome! Major kudos to you, my man - ClassiCube-PPC is a great alternative to Minecraft G4 Edition on PowerPC 7400 systems and lower, especially for creative usages.

I'll link to this in G4 Edition's next update. :)

PS: How viable would it be to port Minecraft 1.5.2 from Java to C? Do you think we could even get newer versions running this way, bypassing Java entirely?

I don’t know if that could be done but it could be a better way to experience the game on lower end systems, maybe not iMac G3’s but other PowerPC Macs.
 
There is a full clean-room implementation of Minecraft beta 1.7.3 called TrueCraft, but I don't even know where you would start with porting release 1.5.2 to C. Even working with TrueCraft's source code, it looks like it would require substantial changes for it to run on PowerPC Mac OS.

You need Tiger at the very least, although supposedly it is possible to compile it for Panther using `-mmacosx-version-min=10.3`

Give that a try and report back.

ok, so I've tried to compile it on another mac using the terminal writing:
Code: 
cc *.c interop_cocoa.m -o ClassiCube -framework Cocoa -framework OpenGL -framework IOKit -lobjc -DCC_BUILD_GL11 -DCC_BUILD_GL11 -mmacosx-version-min=10.3
but I can't find the compiled file

Remove one instance of
Code: 
-DCC_BUILD_GL11
and try compiling again.
 
[mention]mato_Opp_ITA [/mention] try this:
Code: 
 cc *.c -o ClassiCube -DCC_BUILD_GL11 -framework Carbon -framework AGL -framework OpenGL -framework IOKit
