Household DVD player as a ZX Spectrum emulator

Hello, CityAceE By the way, an idea appeared. Why not ask the company itself about all this? [url=http://www.mediatek.com.tw/eng/support/contact/index.htm]Mediatek[/url/? Of course, it’s too unlikely, but maybe Mediatek will be interested in this proposal and will provide all the necessary information and tools. For reference: Each new firmware revision for MT1389 from Mediatek costs to equipment manufacturers (Chinese companies) approximately $20,000, so many manufacturers are in no hurry to update firmware, but only “lick” what they have. In any case, I received this information from the owner of the trade brand of the player that I have at home.

Hello, Vladimir Kladov Vla> Where to put the unloaded toys, where to store the “tape” records or Vla> "disk"? Alas, nowhere... Although why not squeak on the audio output, and who needs it on will the tape recorder record? ;) Or in the free space of a flash drive. Anyway this is the problem is one of the least significant in this task. > The same GORO updates itself when you put a disk in it > update... Like any other player based on MTK1389.

Hello, CityAceE This is what the file selection menu looks like for all devices based on MTK1389: Picture: http://www.ixbt.com/dvd/4tune/mp-151/mp3-05.jpg I think that many people have just such devices at home.

Hello, CityAceE Cit> By the way, an idea appeared. Why not ask about all this yourself Cit> company Well, did you ask? What did they say?

Hello, CityAceE Cit> My English leaves much to be desired, so... I can try, but let’s briefly outline what we need from them...

Hello, antiplagiarism Inexpensive players have 4-8 MB RAM, I haven't seen 32. There is some PC software for the MTK1389 chipset (firmware/reading flash, modification/hacking of firmware, etc.) The player (flash) is flashed: - via COM port and a simple PC<--->MTK data cable (this is convenient for debugging and when "automatic mode" does not work) - in automatic mode, there is a procedure in the firmware that When you turn on the player, it checks for the presence of special. file on disk (in drive) and sends it to flash (convenient for a simple user when updating an old firmware to a new one) The chipset contains 8032, ARM, DSP(?), Servo controller. ARM code can be executed from RAM. Pros: - low energy consumption - ability (with minimal modifications) to work on any player with MTK1389 - it looks like there is an "8bit per dot" OSD mode Cons: - they basically screw up the code of the firmware itself (and not the system globally), for some modifications - it seems the IR remote control is not suitable for dynamic games - the presence of USB or CardReader in players results in a higher price You can start here http://personal.inet.fi/cool/mediatek/documents/index.html Then just google by type mtk1389+arm ZY IMHO, this whole idea makes sense when the player costs up to $100

Hello, Daniel I have this unit: http://bbk.ru/3_25_26_0_287.htm http://bbk.ru/7__75_16_1.htm There is a lot of room for creativity. (There is a USB host, it’s a matter of firewood for the keyboard)

Hello Valen I'm also interested in all sorts of perversions with firmware, I read somewhere how people Tetris I wrote under a digital camera... I personally downloaded the MTK firmware (Chinese Elenberg), and was interested in this topic - I needed the opportunity to contemplate on Russian file names on screen, downloaded firmware both via cable and via disk, itself Russified the menus as expected, but the code is a complete ambush, maybe Now all the docks on the MTK are open, before nothing was clear. By the way there is a bunch of broken firmware for different players, this means that people slowly figuring it out... Regarding emulation, it’s an interesting idea... but nothing more, I don’t think it’s all right just... you can write some kind of tennis (like a video port) for the interface The player menus are real, but the emulator is a mess - it’s all fantasy...
