i completely fail to see what that has to do with the k1, k101, k-team, or their SoC. instead of high-jacking a thread, just start your own.

i tried to contact to maxzhou88 because i want to ask some questions but i see he´s very occupied making the new model of the k1gba.So i want to ask ruilong the next questions:

can i create programs in k1gba without gba,nes,megadrive etc. emulators? Do you have plans to release a sdk for the k1gba? Thanks for reading me and waiting for the answers

+1 on this. I am interested in the Revo (K101), but really want to also create 'native mode' programs for it.

The easiest way to accomplish this might be to offer a Sandbox mode, similar to the Game Gadget. If a certain button is held down during power on, a file on the K Card is load and ran. This way, the normal GBA emulation mode remains intact, but the full power of the CPU and full screen resolution are available to other software.
Here's some info on Game Gadget's Sandbox mode: http://forum.gamegad...utoboot-options

Then it's just a matter of supplying a library, that will run in this mode. SDL would be a nice fit for this.

Having recently developed a few games that run on the Game Gadget, SDL was extremely easy to use and allowed the bulk of the game to be debugged under windows before being compiled for the Game Gadget.

I would be interested in taking on a port of SDL to the Revo, if the boot mode could be provided and a memory map of the hardware provided. This would also involve a port of an older version of Hekkus Sound System (HSS) (http://www.shlzero.com/), and once cleared with the author could be supplied to the community. I did a Game Gadget/SDL_Audio port of HSS; which was supplied to the community.

The mentioned games can be found on http://rastersoft.net/

you can write homebrew for the gba and it *should* work. it seems that code for accessing the faster cpu is not yet available, and there are currently no plans to release a k1 sdk. i've made some comments about the usefulness of a k1 sdk, hopefully in time something will be provided for us. homebrew/emulation tends to propel these devices into popularity, and not releasing something is only going to hurt sales.

i said *should* because in theory all gba homebrew should be working in their hardware solution, but not all of it is functional.

I always welcome you guys' suggestion to K1 GBA SP. I had mentioned this to Maxzhou as Another World also discussed this with me. He said the SDK ( or something else names?) can be released in the future to let K1 sold on k1gba.com can be re-designed the program. But he is very busy this time as we are now arranging the production for the Revo K101. As we said before, the contest for designing the logo for Revo K101 is coming to the end. We had pick out some ones and forward these logo for manufacture. We need them to confirm which one they can print on the device and package. Everything is going well for the new Revo K101.

Maxzhou is a professional GBA gamer. I think he should know what you guys really want. Maybe he will do something for K1 after the jobs for Revo K101- By the way, only the devices sold by us can be called Revo K101 and have our special logo for it. I will share you the final logo for this device later.

Thanks ruilong,anotherworld and cdoty for reply my questions. i am not a programmer and i cant make programs but I ask those questions because some people on the forum www.elotrolado.net are interest on this device to make programs in it.I will spread your answers on the forum...

 

[Another World]

homebrew and emulation seem to make or break these type of handhelds. if they don't release an sdk they will only hurt themselves. its nice to know that maxzhou understands this, i just hope this one-man team has time to do it.

Why the currently K1 not adding the RCT? Because the space inside the mother board is limited, the manufacture can not find enough space to install this chip. Why not headphone port in K1? Because K1 use the design from the original GBA SP.

I appreciate that you want to defend your product, but the original K1 PCB's by maxzhou88 had hardware RTC like Revo K101 - you can see the two crystal oscillators in my post here:-
http://gbatemp.net/t...ost__p__4333985
Will hardware RTC ever be added back to K1 PCB?

Also, as a note for maxzhou88/ruilong I think it would be great if you made a 'K1 Deluxe' GBA SP version at some point, which uses a micro USB charging port and 3.5mm headphone port instead of custom Nintendo port. The rear could look like this mockup picture I made:-

For video out you could use the MHL standard over micro USB, as used by many new smartphones:-
http://en.wikipedia....Definition_Link

Or you could make the micro USB port support video capture on PC, like the DS and 3DS Video Capture Boards:-
http://home.comcast....imar/DSCapture/
http://www.3dscapture.com/

Alternatively, I guess you could just add a standard micro HDMI port?

It just seems a shame to only get composite video output and mono sound from K1, when we could get a nice 720x480 digital signal (HDMI) output with stereo sound.

Currently, we are now finding pads used under the controls to make the d-pad used more conveniently. This pad is the same as what you used on PSP. But you can stick this pad to the K1's Pad and try it. I had tried one and it does work better.

Are the rubber pads really the problem? I would have thought they were the same as the original Nintendo GBA SP rubber pads?
Maybe the problem is with the tactile switches used on the PCB, maybe some different ones might fix the problem?
I think Nintendo uses Mitsumi and Hosiden parts like these:-

No, RTC will not be added to K1 GBA SP. But this function will be added on Revo K101.

The same to Headphone jack on K1 GBA SP, it will not be added to K1 but it will be available on Revo K101.

The PCB and mother board on K1 has enough space, it can not be added too many things. For Revo K101, it is bigger than K1. Thus, headphone jack and RTC had been added.

could there be some addon-type thing?

As I said before- many many times, the manufacture will not add the RTC function on K1 GBA SP. If you really want this function, you can consider about the next version- Revo k101.

It looks like the k sp doesn't support 32mb games,I got a memory out error. I'm disappointed.
(A pokemon emerald rom hack >>)http://www.pokecommunity.com/showthread.php?t=183562

 

[Another World]

i tried some 32 mb stuff while review testing and the only issue i had was that the in-game menu doesn't load. this is a known issue due to the amount of virtual memory that is allocated. the fix is a way to patch things like cheats before the game even loads. the mother 3 translation works fine, although i only played about 30 minutes of the game. i'm thinking that the issue may be with the rom hack you applied.

[raystriker]

What do you exactly mean?

 

[Another World]

2351 - Mother 3 (J)(WRG) works, 32MB game.
2351 - Mother 3 (J)(WRG) w/fan translation works, 32 MB game.
1497 - GBA Video - Strawberry Shortcake - Volume 1 (U)(Rainbow Sparkles) works, 32 MB game.
GBA Video - SpongeBob SquarePants - Volume 1 (U)(Independent) works, 32MB game

the problem is not 32mb games, the problem is probably the pokemon emerald rom hack you linked to. have you tried a clean rom, does it work at all? what is the hack for? is it a RTC patch?

lets be honest here. it isn't perfect, but it does so much right. if you bought it just for a few pokemon games, then i don't know what else to tell you.
