    i think there's something missing. how do you get these numbers? by program? or by sniffing device? i recommend using logic analyzer to debug this.

    Quote from bobbydilley: “Little update: I’ve tracked down the error on the Raspberry Pi - but it’s a wierd one. The JVS protocol works like this: 1. The Naomi sends a sync byte 2. The Naomi sends the address of the device it wants to talk to as a byte 3. The Naomi sends the length of the data it’s about to send as a byte 4. The Naomi sends length amount of data bytes. This all works on a Mac, and all works on a raspberry pi except for step 3 when in a game. In the test menus it works fine, but i…

  • arcade-projects.com/forums/ind…011bd6ce9fcdb85b1e1e12bcb i was going to say something about this from TS first post, but had doubt. But now, kind of sure, that component shown by red arrow was blown. i guess that's a black hole after blown effect.

  • Quote from lukemorse1: “The furthest its been able to go is automatically turning the steering wheel to the left once and then releasing it followed by Motor Error 20. ” i've been curious about this steering behavior. i mean, i saw one cab, it turn to farthest left then turn farthest right. other cab, it turn only a bit angle, then release, it passed the motor test. afair, the rom version on the str pcb, were different, and so these different behavior. the ridge racer v, i think it was using the…

    arcade-projects.com/forums/ind…011bd6ce9fcdb85b1e1e12bcb mobo is biostar g41d3+ v6.3. OS is windows, most likely xp. Surely not 7 or later. The game is PC game : outrun 2006 coast 2 coast, with custom gamepad i/o. There's a license file inside game folder that 'locked' with the i/o bd serial number. That's all i know.

    Quote from stj: “interesting, but unclear - be nice to get the mobo part number - BIOSTAR?? also, where is the game? on the card - or a drive not in the foto? ” will get the p/n tomorrow. the game run from flash disk. you can see it besides psu under cables.

  • Quote from stj: “here is a tip - dont buy shitty $10 chinese rachet crimpers. they will work, but they are optimised for specific terminals that arent really of interest to us. ” agree, but i bought it anyway since i don't know if it's good or not (buying online). It turned out it crappy but can work with a bit effort. could you also suggest which one is good? i also looking for this, especially for JST's.

  • Quote from xodaraP: “The problem with wick is it sticks when the solder cools and you end up making a huge mess with a job like this (I've tried something similar in the past) ” i actually have kind of same problem with wick. so i used coppers from new cable instead (the one that still shines like new). and flux it a lot, i never had it sticks again. btw, with poor heat, you can always use a real 60w solder, they're really kic* ***.

  • or just clean the legs first, then unbend them. use manual solder sucker, or a good solder wick with lots of flux.

    Quote from bobbydilley: “Project Update: Unfortunately a negative update this time, I tried running it on a Raspberry Pi 1st gen today for the first time (had been developing on my mac, but target platform was obviously a Pi) and annoyingly it just doesn't work. I'm thinking that the PI can't process + reply fast enough and so its a speed issue. I will try on a better Pi2 or Pi3 later to see if that helps, or failing that attempt to make the code and linux distro more efficient. So if anyone tri…

  • with some code modification, yes, particularly, the time stamp for each chip. iirc, after sometime, i find out that these 'bad' card showed by 573 games, they're actually caused by 'slow' or you can say 'degraded' flash chip. since konami uses it's own timeout mechanism to verify the card. but actually, the chip itself is still okay, they're just 'slow' a bit. i can't say a lot, because i just have 2 flash card to play with. maybe some other bad card can actually have real bad flash chip inside.…

  • uhm... i don't quite understand what you mean. If you mean, can we use pcmcia adapter that comes with viper h/w. yes, we can. but you need to adapt the pcb footprint.

  • Hello, This is my own private tool, made sometime ago. It is arduino mega shield originally made, because of frustration at konami flash card rarity. Back then, i have 2 'Bad' cards which i hope to be able to check them properly, without having pulled the each flash chip out and test them individually with a programmer. At first, i tried to use this pci to pcmcia card to read them. arcade-projects.com/forums/ind…011bd6ce9fcdb85b1e1e12bcb But apparently, they need a special driver for each kind o…

    I have seen mod board like that. not quite sure how they works. as for cassette error, sometimes because of connector problem. clean it and re-plug.

  • i am afraid you can't use my device, since there's no known cd dumped. the installation routine usually reside on it. the best way to resurrect, like Mr T Guru said, is hand crafting the data, with MAME debugger's help.
