The chips are AM29F160 (8bit wide, 16Mbit in size), no Unlock Bypass command in datasheet
But I can wait that 6 minutes it takes to write full 32Mbit/4Mbytes of data (+12 seconds for erase).

Look in datasheet:
AM29F160
Page 22: (Command Definitions Table 9.)
Unlock Bypass
Unlock Bypass Program
and
Unlock Bypass Reset
Presents in table
Datasheet info:
Publication# 21358 Rev: F Amendment/+2
Issue Date: March 1998
What? You scruwy my balls!!! (то есть выкручиваешь мне яйца!!! )(+12 seconds for erase).
ERASE AND PROGRAMMING PERFORMANCE, page 42:
Sector Erase Time - 0.7-15 s
Chip Erase Time - 25s

ERASE AND PROGRAMMING PERFORMANCE, page 42:
Sector Erase Time - 0.7-15 s

and one chip erases in 10 second, other in 12 second, both erase at same time
and oops, my chips are AM29F016 not AM29F160... 8bit, not 16bit, and I did not see anything regarding fast programming in those datasheets...
..... and now I downloaded another datahseet, and oh wonder, there's unlock bypass command in it... so I quickly went to update my burning utility... but it seems the command is not effective.... things look like they program, but in the end, cart is full of $FF, just like after erase

I think you do not quite understand. There is lock/unlock command to write in sector/chip in JEDEC specification. But. There is unlock sequence to execute this command or simply write command: 555:AA, 2AA:55, 555:AA, etc. So, programming FLASH will be allways take some time to compare with RAM. And ofcourse, there is programming delay to move data in FLASH array.TmEE co.(TM) wrote:..... and now I downloaded another datahseet, and oh wonder, there's unlock bypass command in it... so I quickly went to update my burning utility... but it seems the command is not effective.... things look like they program, but in the end, cart is full of $FF, just like after erase

Well, I figured out my problem.... after chip erase, I forgot to set 82C55 to output data (I was polling chip to see if its finished erasing or not), so unlock bypass command never made to the chip, now things work nicely and I got ~40% increase in programming time
Now it takes ~1minute per MByte.

I found this neat little project recently:
http://www.snega2usb.com/wordpress/
Basically, it's a cartridge USB reader that acts as a USB 2.0 device with a binary rom file on it. I believe this can not only be used for legal emulation of your games but also ROM dumping...

First versions of USB flash cartrige from Masyanya was USB Mass Storage devices too. But then, HDD was fail and Masyanya lost all his work, include this one. And then, new version become not Mass Storage but more complex device with programmable mapper (wich allows play even Beyond Oasis aka Story of Thor with full support of SRAM).Eke wrote:I found this neat little project recently:

Funny, i know this guy. Here we discuss his flash cartrige for SMD and do some correction work. And here he trying do same for SNES. It is same guy because this site is set in his profile on that russian forum.TmEE co.(TM) wrote:That's really nice

Hey, KRIKzz, welcome here!
But....all KRIKzz's FLASH cards doe's not support SAVEs, i'ts tooooo bad, except my cards for SNES, and SEGA... and, my SNES card can make Multigames (with dinamic GameMenu), and can combine LO and HI ROMs in one multigame assemble... aaaand, differend ROMS cand have differend memory space for SAVEs, and not used save ram space hides from card then game running (SNES can see only right save ram size and addresses, i'ts important for classic "original card checks" system, and for Mass Storage: onboard SD/MMC card reader for PC present , and SPI internal machine for SNES present toooooo )... (LOL, not so english language, and not so tematicaly right, - sorry )HardWareMan wrote:First versions of USB flash cartrige from Masyanya was USB Mass Storage devices too.
