I’m trying to run Doom on a price check kiosk.

Hello!
I’ve just been given a Motorola MK1250 price checker from a department store.

It’s running Windows CE 4.2 on an Intel ARM-PXA255 with 32MB RAM.

I’ve managed to stop the store client from running so it now just boots to the desktop, and I’ve got a CF card working through the PCMCIA slot so getting files onto it is sorted, although it seems to delete anything I add to internal memory after a reboot.

My goal is to make it play doom but I have been unsuccessful with both chocolate doom and doom4ce, both claim to be missing files that are not missing.

Can anyone suggest a port to try?

Regards,
James

What files is it identifying as missing? / What is the exact error message, is it missing file or missing entry point?

Chocolate doom says it couldnt find the iwad file, doom.wad is in the same folder though. I have also tried specifying -iwad doom.wad via command line which didn’t help. I also get a failed to allocate <amount I forget> memory sometimes but not always.

Doom4ce just says something similar to “could not find DOOM or associated files” I can’t remember the exact wording.

I might be totally wrong but I’m wondering if maybe there’s a problem with non-factory applications having access permission? It’s a complete guess.

I'm not familiar with the security features of Windows CE .NET used in kiosk situation, but if I were the integrator, I would lock it up, since it could be an entrypoint to get into the corporate network / inventory network...

But that aside, I can imagine it being fun to play doom on the kiosk. lol

Can you try the shareware WAD?

What does https://www.hpcfactor.com/scl/1035/Gamefreaks/Doom?page=details do?

It gets further than anything else and actually tries to load but then this happens:

This is Chocolate Doom with the full IWAD path specified. I actually get a different error if I specify a .WAD file that doesn’t exist. (I made a typo the first time)

This is Doom4CE:

For chocolate doom and doom4ce, are there any directory requirements? HPC Doom looks for the IWADs in a specific folder but from what I can find the other two just look in the same folder as the EXE?

0xC0000005 is a CPU level access violation, probable RAM or (lack of) page space related.

Doom4CE requires GX.dll, so you need to install GAPI ( https://www.hpcfactor.com/scl/380/WinCESoft/Game_API_GAPI/version_4.... ) or a GX stub

Ah that helps, this kiosk has 32MB of RAM and has a slider in the system settings to choose how much is used as storage space, I may have to lose some RAM to increase the page file size. Do you know how much page file doom needs?

I did install the GAPI CAB file, should that be enough? I noticed one of the doom ports had gx.dll in the program directory, does Doom4CE need that? Or is the default install location from the CAB fine?

I have no idea on requirements.

As long as there is a viable gx.dll in the search path i.e. the application directory or /windows/, it should suffice.

Make sure that GAPI is working through the utility.
