Nintendo DS port (Alpha 6)

[AntBUK]

You used a program, mines done by hand .

Fair enough yours looks better, except for the top screen

Nothing more annoying then this though... And it's slightly annoying when loading Moonshell

(sorry about the image quality, crap camera on my phone )

[elf_sander]

You still use usrcheat.dat?
You know you can put all your own cheats in the cheat.dat from the R4 team.. don't you?

And I created my program, so that's better than drawing by hand

Also, I do like my top screen images better.

edit: version without the "no cheats" button http://www.ndsthemes.com/themes/details/559dbe7450

[AntBUK]

I prefer to keep my cheats separate

I was looking for ages on NDSThemes for an openttd theme That's why I made my own in the first place

Really nice work you did there! I can't wait to see this on my DS at home

I don't know how you implemented scrolling, but here's my take on it :
Holding left tab activates scrolling mode.
While in scrolling mode, directional pad scrolls top screen and touching the bottom screen will scroll it.

Here it is, the very first sneak peak at my Nintendo DS port. While it looks pretty much the same as the last screenshots I posted, a lot has changed internally and it is running much smoother now. Through the elimination of the wasteful _chatmessage_backup (a 440KB global variabl ) it is now possible to load bigger maps, up to 128x256.

Other notable changes are:
- based on r11844
- maps up to 256x128 running (but saving only works for 64x64 right now)
- saving and loading works
- in openttd.cfg you can define a path where your data resides
- loading time greatly reduced from 45 seconds to 15 seconds
- rewritten the blitter to free 96KB of main RAM

Some serious bugs still remain:
- pathfinder crashes
- open road station gui, then click on road depot icon -> crash
- station gui crashes / not displayed correctly

To get it running you probably need to DLDI patch it. I have a R4DS card which takes care of patching by itself. Please report any bugs / hardware issues here.

- maps up to 256x128 running (but saving only works for 64x64 right now)

Saving works by creating copy of the map (thus requiring twice the memory) and then compressing/saving it on background. If you alter the behavior to pause and then create the save from the local copy, saving might work for larger sizes too.

Wow.. this is awesome..

I have a big bug to report, the game crahses when you have a window with a second view open (like the train/road vehicle/etc window) or when you try to do multiple things at the same time (build a track and a train depot for example)

This is so awesome! I was actually thinking about trying this myself, I'm a student in software engineering, and have made a few test apps for the DS, so if you want a hand with this, just let me know (But I understand if you want to do it yourself, too )

At the very least I'll be as active as possible in reporting bugs!

Same here, only my best DS creation was "Hello World! From Sander" I will at least test every version with a huge bughunt.

[AntBUK]

I'd better stick my DS on charge, woohoo!

I killed YAPF in an attempt to avoid the path finder bug

I just wanted to reply and say thanks a lot. I was (am?) a big fan of TTD and I had no idea there was an OpenTTD. Now to also find a TTD for the DS being worked on... well, I am impressed.

I have one little bits of feedback:

1) your readme seems to imply that the .cfg should be pre-ready for everything being in /openttd/ folder, but really it points to like /gamedata/openttd/ instead. It took me a few tries to fix this.

2) the icons are all squished, makes meh cry! (I'm sure you know this)

3) uh, nothing else... these things are just better in 3s. really looking forward to future versions of this... could you maybe come up with your own little page or something, so I don't have to keep finding a forum topic?

[dominik81]

Thanks for all the feedback. It would be great if you could also write what card you are using.

I supplied a diff to the repository and appreciate it any patches, bug fixes are most welcome.

Hmm, I'm not sure those are the same bugs I know. You mean it even crashes for you when there's only one vehicle window open?

Thanks, I didn't notice, it's fixed now. I use /gamedata/openttd myself but thought that I changed it for the release.

2) the icons are all squished, makes meh cry! (I'm sure you know this)

No, I didn't. Ididn't know you cried over it.

Ok, Using R4DS (firmware 1.15) and the train I made doesn't want to arrive at the station. It works fine in the Jan 14th nightly.

NPF doesn't make any difference and re-enabling YAPF comes back with...

Code: Select all

2A4 sprite> Compacting sprite cache, inuse=286312 terminate called after throwing an instance of
'std::bad_alloc' what():  St9bad_alloc

Save attached.


Also, is the random seed meant to be locked at 1337?

Really need a keyboard interface as well.

When I tried to do the same without any vehicle windows open, it still crashed.. So it's the path-finding bug.

I'm glad someone took the time to try a DS version. I wanted to see one ever since the PSP got a version.
I tested on my R4DS. Took a while to get it working, and it crashed when I tried to connect the coal route, apart from that... Good work!

I cant wait to try out the next version. Adding a random variable should be your next task.
All you need to do is ask the player to press Start, and generate a random number based on the time that they waited before they pressed Start. I did the same with my Homebrew game.

With a few modifications to the .cfg file I got it to work on a DS-Xtreme card. The only problem is, after about 30 seconds everything freezes and nothing will respond again... Which, of course, makes it rather useless.

But, I have to say: great effort! Keep up the good work! I'll keep testing on my DS-Xtreme Card.

[fryfrog]

I tested it on my new CycloDS, which is the black version having their hw 1.1 or something. The auto-patching DLDI worked fine, my only problem (as mentioned above) was having to fix the .cfg file, no big deal.

[cardinal808]

I've tried it yesterday, but it gives an error. "no available language packs (invalid versions?). I Used an R4... no clue what to do.

Im looking forward to this version. It's a Great idea. Good work

[Slye_Fox]

I'm working on a few menus.

Should they be orginal sized, but condenced to fit on screen.
Or use the smaller icons like the tool bar?

It's because of a small oversight dominik81 made. He uses /gamedata/openttd on his card, and has his .cfg edited for that, and he forgot to edit it back before releasing it. He reuploaded it with this fix so you can now put the openttd-folder on the root of your card like the readme says.
