As the title suggests, does our dosbox jit support ipxnet?

I have enabled it on the .conf (ipx=true) but when typing ipxnet inside dosbox I get an illegal instruction.

Therefore I can't connect anywhere. Any thoughts?

No one?

I tested DOSBox_0.74SVN and the same error persists.

I asked Walkero and he also checked that OS4 Dosbox jit spits out same error (illegal command).

So, is this a thingie on both MorphOS and OS4?

[ Edited by Cool_amigaN 09.04.2022 - 00:22 ]

Checked the 68k version and it states on the ReadMe that network is not supported.

So, back to square one: supposing our dosbox version(s) don't support ipxnet as well, is it possible to recompile the program, taking advantage of latest SDL2_net lib?

AmigaOS4, DOSBox version 0.74-3 based on SVN r4293 works for me.
according this manual ipx manual

tested now with AmigaOS Sam440ep-flex and Pegasos 2 with command IPXNET STATUS
not tested with real game

Powermac G5 with MorphOS have also illegal instruction.

@sailor

Thanks for the feedback. Indeed I can confirm with Walkero that ipxnet works on OS4.

Can anybody further test our own (MorphOS) version, so we can conclude whether it's affecting only our own platform or both me and sailor are doing something wrong?

Have you tried to contact Michal Zukowski who ported the latest version? Maybe he has an idea why this is not working.

@Walkero

Yeap, I already have since many weeks but no news unfortunately, so I ended up creating this thread because I originally though I was doing something wrong from my end.

Sailor though, confirms the "illegal instruction" too on MorphOS :/

As far as I understand, dosbox can be compiled with or without ipxnet support. Perhaps there is a chance it was left out unintentionally or perhaps the SDL_net lib by that time did not support it (or I am still doing something wrong), Idk.

I've started checking what is wrong with ipx. Will inform you probably tommorow :).
Ok, checked, ipx support isn't turned of during compiling.

Ok, please check this version:

Hey thanks for your prompt reply and happy to hear this can be fixed :)
I get however a "file is not executable" error, despite having the executable attribute enabled. Tried via cli and Ambient, no luck.

Edit: Nevermind, I redownloaded and now it boots, I can connect to external public network, I can connect from pc dosbox to morphos (and vice versa), game sees the ipx network but ultimately fails to connect to the game server.

However, perhaps it's the particular game, I 'll dig a bit further and revert back to it. I think we are getting somewhere :)

Oh, btw, if your run 2 dosbox instances next to each other, the second produces the following error: SDL: Failed to create overlay, switching back to surface

[ Edited by Cool_amigaN 09.04.2022 - 02:09 ]

Right, You can't have two overlay surfaces/windows at the same time.

Initial tests between MorphOS / Win DosBox versions:

- Warcraft fails (game doesn't join - tried both as server and as client)
- Doom2 fails (game doesn't join - tried both as server and client)
- Syndicate Wars works (tested connection only as client)
- SWOS PC online patched fails (game doesn't find match room to join)

In all cases dosbox cli output clearly indicates a connection to/from a certain IP.

I will continue running tests with more games but we need to establish a bare minimum test scenario imho. We could start with Doom2 as one of the most played-to-death multiplayer ipxnet games.

- Duke Nukem 3D Atomic with MorphOS as both server/client, results into PC DosBox crashing when connected, error: ListenForIpxPacket: 0x, Null pointer assignment.

[ Edited by Cool_amigaN 14.04.2022 - 14:10 ]

Update:

- Death Rally: works as MorphOS server, fails as MorphOS client

- Tyrian: Fails both as server and client

- Dosbox: ipxnet status reveals client/server connection but when doing ipxnet ping results are empty (nothing to show) - edit: even with 2 local instances of MorphOS dosbox on the same system, is this normal?

[ Edited by Cool_amigaN 14.04.2022 - 14:12 ]

Update:

- Mortal Kombat 3 works, tested both as server and client

- One Must Fall 2097: Fails, tested both as server and client.

I think the results so far don't make any sense to me :/

Anyway, should I test more? Could MorphOS UDP which goes over IPX failing somehow?

Think the fact that DosBox can't ping itself is worrying.

@ Sailor & Walkero

Hey, can you pls test any given game of the above, in order to verify whether OS4 dosbox ipxnet port suffers from same symptoms?

Some test case scenarios between OS4-OS4, OS4-PC or OS4-MorphOS would be great.

If you want the sources for any of the above games, let me know so I can share (but start with a simple ping command after establishing the startserver/connect to ipxnet which fails here).

Alternatively, you can check THIS link for more titles featuring ipxnet. Choose any and let me know, so I can double check from my end as well.

:)

@zukow

Returning to this issue, is it possible that you or someone else can have a look at it?

If we manage to sort it out, we can finally add online multiplayer support on the Real Amiga SWOS Total Pack.

Think this would be a truly unique feature to our available gaming library but we need your assistance to move forward with the project.
