The psp port was quite old last time i checked (0.71 or so).
Does the game work for you on your pc?

not realy I know I got it once but it is a year or so ago
now it just crashes if I want to start it with dosbox on my pc 😊
if I run it with dgvoodoo and VDM sound it crashes also

Well then get it working there at first before playing with the psp port.

Be sure to install the game within dosbox.

Hello the second time 😊
I tried to run Tomb Raider on my pc with dosbox version 0.72, too
I tried to mount my drives like I had to do on my psp.
mount c: c:/
mount d: c:/cd -t cdrom -> because the psp has no CD drive 😁

like on my PSP I got the Laserlock error so I replaced the Dos4GW with one from the Internet. After that I was able to install Tomb Raider I did it with "No Soundcard mode" because on the psp I have non, too.
But if I run tomb.exe Dosbox crashes - like on psp- and I really have no idea what this error code wants to tell me

1MIDI: Opened device :win32

could it be a problem with the DOS4GW I downloaded because of the Laserlock problem? If I don't get it working on my psp atleast I want to be able playing it on my computer

PS. Dosbox is cool 😎

sorry I can't find the edit button.

I got TR running on my computer now, but only with the Tomb Raider advanced Installer which includes dgvoodoo and VDM sound.
With dosbox I can run the test for sound during the installation but I can't run the tomb.exe it chrashes with the error code above.
On my psp I got a sound setting with which I can run the sound test too, but the tomb.exe crashes with the memory and dos4gw error and I can't run TR with the advanced installer on my psp (yes I tried it but I got a curious screen with manufactoring date of my psp and so on 😁 )
Can someone explain me the errors I got so I can experiment with the regarding settings ?

I've been working to support LaserLok in DOSBox, with - perhaps - some success (Championship Manager 2 works, others might but I don't own them), but it's only a source patch right now. You'd have to build the code yourself.

Okay, now I've looked at this one. The memory range error is caused by heap corruption in the emulated memory. Something is loading a file into a memory block that they don't own. It's completely reproducible, so someone has a bug. I'm not sure yet if it's DOSBox or TR itself.

Anyway, once that error is seen, DOS4GW wants to exit to DOS, but forgets to return to real mode first before loading a selector with a real-mode value. This causes a GPF, which causes the unexpected interrupt and the second error message.

I'll keep digging when I have time.

Don't care too much about that, usually those issues are game+extender bugs
(exiting during critical code when in a graphics mode for example).

Oh, I know exactly when and why the second one occurs. Agreed, that's not a bug worth fixing. However, the first error is serious, and I don't know exactly when or why it occurs (ie why the file is loaded to the wrong location). That cause of that bug does need to be identified, because it might be in DOSBox itself.
That's what I intend to find out when I can.

wow, that seems very complicated. thank you very much you two.
unfortunately I don't know very much about dosbox so I am cheerfull that there are some guys who could help me 😀

greatz
