# game collection
Good for play on Kindle. To be filled.

[notimp]

Let me be the first to say - you sir, ROCK.



Cheers, n.

edit:

Could be neat to get a little collection of games together that would make sense to be played on a Kindle (slow paced, ... maybe text focused...) --

Detective Conan - The Mechanical Temple Murder Case
http://www.romhacking.net/translations/2151/
(works fine - part of the gameplay has screen scrolling)

Shadowgate
https://www.youtube.com/watch?v=GzM0v7CWdIQ

other potential candidates:
The Fish Files
Scooby Doo! Classic Creep Capers
Mario's Picross

edit: Those three are partly untested. I'll test them asap - would make more sense to actually post games that someone has tested already and that are working.+

edit2: In addition to being slow paced, games also shouldn't rely on full screen scrolling too much - because with the low refresh rate of eInk - if the entire screen starts scrolling, you wn't be able to make out much of whats going on. Fixed backgrounds and a few moving sprites are preferable.
...

edit3: Setting frameskip to around 30 makes scrolling backgrounds a little more legible. At the expense of frames of animation of course.

thx liim,

just a little warning for KT3/800x600 users:
The in-game menu bar is not made for this resolution, all menus are cut short.
No way to reach the quit option in file menu, frame skip cuts at 11 and turbo speed at 9.00.
You are going to be left with an alternative quit of the emulator!
Playing works fine though.

[Mr. B]

I tested Boggle Plus on my Kindle Voyage and it's perfectly playable. Zoop, a puzzle game, is mostly playable.

One major issue, when I'm in game and go to load a new game, I end up with a blank screen with only the horizontal status bar at the top. I have to restart my device because I get no response from swiping or touching around the screen.

same here...you have to close the game before loading another one.
Any source code liim?

Tetris works pretty good as well.

Confirmed. Should be fixed in version 1.7.

Now works fine to open a game without closing.

Still have the frame skip menu cut off.
May i suggest to invert it, so it starts with 60?

great work

And the source is where?

The only closed source that this forum deals with, is that provided by Amazon/Lab126.

You need more than just the open source license, you need to provide the source or a link to the source.

I'm not sure what’s going on on your device.

BTW: Did you try Gnuboy? Maybe working on old model.
I made Gambatte-K because it’s not working on pw3.

Ok, I archive them form the version control system.

hi liim,
ok i'll put some screenshots below.

My wild guess would be, that you do not acount for the resolutions different models have.
I have a KT3 hence mine has a 600x800 pixel resolution and that is not enough for the menu bar, it seems.

K2, K3, K4, K5, KT2, KT3 = 600x800 px
PW1, PW2 = 758x1024 px
DX, DXi, DXG = 824x1200 px
PW3, KV = 1072x1448 px

(i'm sure i missed one and kindle police will make me aware of it)

EDIT: Don't get me wrong it IS working perfectly!
There is just no way to change frame skip or speed more than you can see in the screenshots below.

EDIT 2:

May i suggest to invert it, so it starts with 60?

What i was suggesting is a quick dirty fix without messing too much.
src/gtk/main.cpp - line 308 - 311
from :

int frameskips[21] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9,
                          10, 11, 12, 13, 14, 15,
                          20, 30, 40, 50, 60
                         };

to :

int frameskips[21] = {60, 50, 40, 30, 20, 15, 14, 13, 12, 11,
                          10, 9, 8, 7, 6, 5,
                          4, 3, 2, 1, 0
                         };

and src/gtk/main.cpp - line 326
from:

float turbospeeds[11] = {0.25, 0.5, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0, 10.0};

to :

float turbospeeds[11] = {10.0, 9.0, 8.0, 7.0, 6.0, 5.0, 4.0, 3.0, 2.0, 0.5, 0.25};

This would make the menu options usable on my KT3 and wouldn't change much on your side.

thx for the source
greetings wodan

Hmm, I didn't see any mention of a version control system in your first or second post.
If I had, I would not have asked about the sources.

Another note:
Kindles run Linux not Windows.
Filenames with spaces in them may be too hard for newbies to handle on Linux.
It would be a bit more friendly to the non-technical users to not have spaces in the filenames.

Actually no. You can manually modify the config file “/extensions/gambatte-k/bin/config”.
If really want a change. My advice is a new dialog, like this

Btw: I event reluctance to move the recent files menu to a submenu, after that one more touch/click is needed. So I will not make this change to complicate things. If you want, then DIY.

What I am seeing the real problem is the virtual button layout is not harmony, select/start/A/B are too big. I forgot to make them auto fit size.
You can adjust the “void DrawingAreaJoystick_draw(GtkWidget *widget)” function.

I don’t think “non-technical users” will jailbreak their Kindles, install extensions, and get ROMs to play with Gambatte-K. Although it’s not really playable.
And “spaces in the filenames” matters? Nobody force you extract the archive in console/command.

Btw: Linux is simpler than Windows, no UTF8/OEM code convert needed. Well, no business with English country people.╮(╯▽╰)╭
