Re: DOSBox 0.65 ... ftw

It's really remarkable how much Arnim has given to us lately, besides all the awesome work on DOSBox.

New Port: Warzone 2100

New Port: Jagged Alliance 2 Engine

New Game: OpenTyrian 2D space shoot-emup!

Thank The Maker... Welcome back.

Re: DOSBox 0.65 ... ftw

Here's a fairly typical oprofile run for recent dosbox
running wing commander, vga, cycles 1600, frameskip 5 sound is somewhat sputtery. The breakdown was pretty surprising to me - due to high frameskip and dirty buffer technology vga and screen blits accounts for only a few percent of the cpu use.

Code:

CPU: ARM V6 PMU, speed 0 MHz (estimated)

Counted CPU_CYCLES events (clock cycles counter) with a unit mask of 0x00 (No unit mask) count 100000

Re: DOSBox 0.65 ... ftw

Hi ArnimS,

Thank you first for the great job, I really enjoy Dosbox but still have the same issue that the mouse cursor doesn't follow the stylus. I searched in this thread but couldn't get an answer. Could you please let me know it will be fixed or there exists some solution already? Thank you. It's quite annoying because one of my favorite DOS games is heavily relied on Mouse.

-Yichun.

Re: DOSBox 0.65 ... ftw

Greetings again ArnimS.

Hey, I sort of felt that your recent mental snap had something to do with a post I made earlier on in this thread.

I know that you just said for your comment to be ignored, but for some reason, I feel like that's not enough to resolve what you said.

Your suggestions on how to correct the mapper.txt function, I already tried them all even before your reply. I'm not one to immediately run to this site and complain about something going wrong. I first try to work the problem before posting here.

With that being said... Yeah, there is some weird, little bug in your build, I just can't seem to place it.

I've got a ton of possibilities on what might be the cause of this, but my best guess is that it has something to do with the fullscreen option in Dosbox. Honestly though, I could care less about that.

Your comments using the F bombs and on eating rice.... well, first off, I've never heard that expression before. To me, it seemed like it was either an Eitheopean slur or an Asian racial disparagement.

I'm not judging you on what you said, only because I couldn't understand it.

If this had nothing to do with what I posted earlier, I will give you my fullest apologies for this current post.

However, If it was something that I did in fact say, well, next time, at least give me the chance to apologize first. :)

I still think of you as a good person and a nice friend that helps me whenever I ask a stupid question, so no hard feelings, okay?

I hope things are going well for you.

Cheers buddy. :)

Re: DOSBox 0.65 ... ftw

hello hello... HOW do i install this beautiful program onto my beautiful new N800 tablet? I've downloaded almost every file on the source site by you arnimS.. I've also scanned through every single page on this thread.. So anyone have nice straight through directinos I and others can use , what to download, what to install and how, to get dosbox working the best it can so far on the N800? Any help. MUCH.. appreciated.

Go to http://pupnik.de/dosbox.html in your tablet browser,
click on the OS2008 .deb

No messing with config files, necessary. It should work regardless of whether you are on N800 or N810, OS2007 or 2008. If you have a problem, post it here.

This version fixes the N810 keyboard problem with the missing number (fn key). Also adds some minor optimizations.

I've been able to get mouse working accurately in two mouse games so far. DOSBox can auto-calibrate mouse to screen dimensions. To do this drag stylus slowly across the fullscreen game window, left to right and top to bottom; you may need to do this more than once. If you find that mouse is traveling only in upper-left hand corner, then you'll need to edit dosbox.conf to scale the mouse motion. For example Betrayal At Krondor needs sensitivity=200, but then the mouse positioning is ~perfect~!

Re: DOSBox 0.65 ... ftw

Oh wow, thanks! :cool: I'm off to try this new version out right away!

Re: DOSBox 0.65 ... ftw

Arnim, i can report that this new version doesn't take game as an argument and doesn't automount its directory. :(
