Discuss Mikhail Tkach's InfoNES port

[criznach]

I'm starting this thread for anyone looking to discuss the InfoNES port by Mikhail Tkach (MikeT).  I found the issue page and have been tinkering with it for a few days.

Currently the sources are available at:

There is some discussion of patches here:
http://www.rockbox.org/tracker/task/2911#comment18694

Anyone read japanese?  The sources contain a GPL2 file, but I can't read the readme to be sure.

Later,
  Chris Miller.

[MikeT]

I'm not sure if its GPL2. I just assumed that it is.

I've been trying to debug it, but so far no progress.

If you can't read the README, run it through Babelfish.

Though the translation may be very rough and literal, it should at least give some answer to the question... without coming up with 42.

[criznach]

SWEET.  I had no idea babelfish would do japanese.  I'll try that.

MikeT: what's problems are you running into?  What platform are you building for?

[Chronon]

It is a translation of the GPLV2.  

I'm having a little trouble parsing this part of the Babelfish translation, however:

Above Note * * The English document (GNU General Public License) it makes the formal document. As for this Japanese character document adopting the opinion of the attorney, being something which 翻 translates the English document as accurately as possible, the あ る, is not the contract which legally is effective.

Some more info here on japanese translation of GPL2.

It seems that if the English version is includes, it officially falls under the English version.

I've emailed the author to see what he says.  Not sure if he reads or speaks English, but he has a good translation of his InfoNes Page, so hopefully.

I'm building for Iriver H10 simulator. The buttons don't work correctly and I have to kill the sim in order to exit.

[criznach]

I've got it running well enough to play megaman 3 on the ipod 5.5g

Yeah, I have to reboot the iPod to get out too.  I just posted a patch with my ipod changes to the issue tracker.  I'll email it to you too.  It runs a lot better with frame skip enabled.  Does the iriver have a scroll wheel?  Maybe you can use the scroll wheel code.

Rockboy uses the hold button to switch to a menu with quit at the bottom.  Would that be cool for InfoNes too?  I think we could easily incorporate a similar menu.

[Mad Cow]

The H10 uses a simple up-down scrollpad, a "back" button pointing left a "select" button pointing right, plus pause/ff/rew buttons on the side. A button map should be simple.
EDIT: The newest version of the diff already has H10 button mappings which should work. Have you tried an normal build?

Also, could you try to port the screen rotation code from rockboy or mpegplayer? That would allow the gigabeat to use that 1:1 ratio code of yours. Does the menu even work right now? I tried and it didn't actually do anything when you selected an option, it just showed a dialog box with the name of the option.

I think screen rotation would be slower than the 1:1 code because it probably has to be drawn one pixel at a time.  But it wouldn't be hard to do.  Is gigabeat always rotated on rockboy?

You mean the menu in rockboy?  I guess quit is the only option I've tried, and I know it works.  I haven't personally done anything with a menu in InfoNes, and I didn't know there was one.  There are a few dummy functions but I don't think they do anything.  I was going to work on that later tonight.

I was talking about the dummy menu in infones. There's an option to rotate in rockboy, and it's rotated by default on mpegplayer. I think rotation is done in the LCD controller, because I don't think that there's any loss of speed in rockboy when it's turned on. maybe look through the cod eand see what's up. I tried, but couldn't find/understand it.

So it seems that the NES emulator is really making progress. Can I expect to see this released in svn by late november or early december, or any time at all?   Thanks for making rockbox even better.

Do you have sound working yet?  I haven't tried your patch.

[MikeT]

No, no working sound unfortunately.

The rotation code is in lcd.c starting around line 830.  This is similar to the way that it is done in doom as well.  It is not performed by the controller, but it is very fast.  It is using fixed point calculations to scale and rotate based on the source and destination screen sizes.
