jaredjames Posted April 28, 2017 Share Posted April 28, 2017 Hi everyone i got this rygar board im assuming its a bootleg [ATTACH=CONFIG]109225[/ATTACH][ATTACH=CONFIG]109226[/ATTACH][ATTACH=CONFIG]109227[/ATTACH][ATTACH=CONFIG]109229[/ATTACH] the guy i got it off said it was going but thought the monitor had died because it would not get a picture except sometime random garbage would come on screen i tryed another board and the monitor works so it must be the board i wired up a jamma adapter and turned it on and just black screen that sometimes shows garbage and i can hear some background noises sometime witch sounds like the game is playing Any ideas of things to check first it seems to be getting power across the board maybe some bad roms cpu maybe im just learning so this is all new to me i have a eprom programer and logic probe if that helps i was also wondering if someone could tell me what the two boards attached to the main boards do? [ATTACH=CONFIG]109225[/ATTACH] does anyone have a schematic or can tell me what the different parts of the board are Thanks Link to comment Share on other sites More sharing options...
jaredjames Posted April 28, 2017 Author Share Posted April 28, 2017 i also found a few different pinouts could i be using the wrong one maybe? Link to comment Share on other sites More sharing options...
Womble Posted April 28, 2017 Share Posted April 28, 2017 The main board is normally refered to as the CPU board, that runs the program, and the other large board is usually the graphics board, however things are often not as clear cut. The small daughterboard is there to replace a custom IC thats on an original board. The bootleggers tried to avoid redesigning the boards, and as the custom IC can be replicated with a lot of individual chips they mount a daughterboard at that location to avoid having to move everything else around to make room. Having said all of that.... Remove and reseat both the ribbon cables, and remove and reseat the daughterboard. The BD will have a few rows of pins that sit into sockets on the main board. Be careful you get the pins back in the right place and without bending any. That process can often chase away a lot of gremlins on multiboard systems.

What are you getting on the 5V rail? At the board (not at the PSU), measure on both boards too. Measure across any of the 74LS ICs.

jaredjames Posted April 29, 2017 Author Share Posted April 29, 2017 im not getting any picture now just static from speakers with faint sounds of the game every now and then i reseated all boards ribbons and rom chips and no change i did notice the back side of the board was dirty looked like something had been spilt on it all the 74ls chips were getting 5 volts i also messured 5 volts across the whole board except the z80 on the daughter board is getting voltage drop only getting about 3.4 maybe i need a new socket for daughter board? maybe new z80?

Womble Posted April 29, 2017 Share Posted April 29, 2017 Were you measuring across the Z80 to the right pins? They don't follow the same pin pattern as 74 series chips. Link to comment Share on other sites More sharing options...
jaredjames Posted May 3, 2017 Author Share Posted May 3, 2017 what pins do i test for power on the z8o? i just got a logic probe so i can test it any idea where i could find out what each pin should do on my logic probe ive been looking for datasheets just not sure if i found the right one Link to comment Share on other sites More sharing options...
Aussiekanga Posted May 3, 2017 Share Posted May 3, 2017 http://www.digital-circuitry.com/IMAGES/webpage/MyLAB/Z80.jpg Check Reset pin 26 should go low then high on power up if its going low high all the time back and forth its stuck in watchdog Check Clock pin 6 should have a pulse Theres a basic write up on how things work that @Womble did i just can't find it have a read of that first Post up a photo of what you get on screen at the moment might give us all a idea on what the issue could/maybe Link to comment Share on other sites More sharing options...
jaredjames Posted May 3, 2017 Author Share Posted May 3, 2017 pin 6 just read 0 (witch i guessing is low) with no pulse and pin 26 was nothing none of the pins i tested on the chip read a 1(high) witch i found to be wierd does this mean that the chip is bad? or maybe i'm doing it wrong https://www.youtube.com/watch?v=ijiyQL5Pbdw this is what happens when i turn on the game sometimes the screen just stays black other times it does this but speakers start to crackle and can hear random sounds from the game Link to comment Share on other sites More sharing options...
repuken2 Posted May 15, 2017 Share Posted May 15, 2017 Hi guys, i just got this very exact bootleg Rygar pcb, i think i got it running but video is completely off. I followed the 22 pins pinout that's floating around and seems to be the most common: PARTS SIDE SOLDER SIDE --------------- ---------------- 1 2 LEFT 1 2 RIGHT 2 2 DOWN 2 2 UP 3 2 JUMP 3 2 ATTACK 4 KEY 4 KEY 5 1 LEFT 5 1 RIGHT 6 PL 1 DOWN 6 1 UP 7 PL 1 JUMP 7 1 ATTACK 8 RESET 8 SVC 9 PL 2 START 9 PL 1 START 10 COIN 2 10 COIN 1 11 GND 11 GND 12 GND 12 GND 13 GND 13 GND 14 SP 14 SP 15 +12V 15 +12V 16 +5V 16 +5V 17 +5V 17 +5V 18 +5V 18 +5V 19 SYNC 19 VID BL 20 VID GN 20 VID RED 21 GND 21 GND 22 GND 22 GND but i think video pins are not correct and i suspect they're at the bottom, in the last 4 pins, in place of those 4 GND. jaredjames, would you mind sharing your video pinout and/or a closeup of your adaptor please? Thanks a lot!!!

channelmaniac Posted May 16, 2017 Share Posted May 16, 2017 Is there a 5 or 6 pin connector all by itself on the board just for video? Link to comment Share on other sites More sharing options...
repuken2 Posted May 17, 2017 Share Posted May 17, 2017 No, just a 22 pin header , my board is the very same Jaredjames showed in first post pictures. A bootleg board. I went ahead and soldered 4 video pines, they would be the last 4 pins in parts side, positions 19,20,21 & 22. It looks like this: 2P Right | A | 1 | 2P Left 2P Up | B | 2 | 2P Down 2P Attack | C | 3 | 2P Jump | D | 4 | 1P Right | E | 5 | 1P Left 1P Up | F | 6 | 1P Down 1P Attack | H | 7 | 1P Jump Service | J | 8 | Reset 1P Start | K | 9 | 2P Start Coin (2) | L | 10| Coin (1) GND | M | 11| GND GND | N | 12| GND GND | P | 13| GND Speaker | R | 14| Speaker +12V | S | 15| +12V +5V | T | 16| +5V +5V | U | 17| +5V +5V | V | 18| +5V VIDEO BLUE | 19| UNKNOWN VIDEO GREEN | 20| UNKNOWN VIDEO RED | 21| UNKNOWN VIDEO SYNC | 22| UNKNOWN The electrical part i guess it's ok since the games starts and runs ok, you can coin it, hear the roar, then press start and hear the introduction music and then the game fx when atacking or jumping. One thing i noticed is that i had to crank up the psu by a little, otherwise the game would reset randomly. The only thing i couldn't get to yet is the video to sync, i've been a big while turning the pots of the monitor, h-hold and verticals and it still doesn't sync correctly. It would be nice to know what the last 4 pins are for the SOLDER side (19-22), maybe i'm still missing something. Link to comment Share on other sites More sharing options...
channelmaniac Posted May 17, 2017 Share Posted May 17, 2017 If you have a logic probe with audio capabilities, it's very easy to ID the video and sync output pins by their sound. Link to comment Share on other sites More sharing options...
repuken2 Posted May 17, 2017 Share Posted May 17, 2017 Thanks channelmaniac, i don't have a logic probe right now, i should get one of those. I already have identified the video output pins, i was just hoping somebody has the full pinout of this board, to make sure everything is in place. - - - Updated - - - BTW: in case i had one logic probe, how do you recognize each signal by their sound?

repuken2 Posted May 20, 2017 Share Posted May 20, 2017 Thanks spez778 !!! My board has that very same pinout, except for the last 4 pins on PARTS SIDE: Thery are: 19 VIDEO BLUE 20 VIDEO GREEN 21 VIDEO RED 22 SYNC what i don't know is what happens with the other side, the SOLDER SIDE , those four pins. I didn't tried again but i couldn't get it to sync with my monitor yet. That's why i was hoping somebody had this board's complet pinout, maybe other side are ground or somehing. Regards.

buttersoft Posted May 21, 2017 Share Posted May 21, 2017 If you have a logic probe with audio capabilities, it's very easy to ID the video and sync output pins by their sound. Another question, just because i'm curious - what do they sound like? 15kHz whines? Link to comment Share on other sites More sharing options...
channelmaniac Posted May 21, 2017 Share Posted May 21, 2017 Another question, just because i'm curious - what do they sound like? 15kHz whines? Connect them to a working board and have a listen. It's hard to describe. Sync will have a repeating audio cadence that the RGB outputs won't have. Link to comment Share on other sites More sharing options...
repuken2 Posted May 21, 2017 Share Posted May 21, 2017 Thanks a lot !!! Very much appreciated info !!! I guess that's how sync will sound if interpreted as an audio signal. At last i got it working perfectly, it needed a boost of the PSU, otherwise it would not sync at all. Thanks a lot to everybody for you input !!!! Now let's get to the round 27 !!! :cool: Link to comment Share on other sites More sharing options...
steptoe Posted October 12, 2017 Share Posted October 12, 2017 (edited) Hi guys I have a bootleg rygar as well, cant work out the pins. Pin 20 is vid go and red, 21& 22 are ground, the pic below shows the three of them being connected via the pcb, does not make sense. I used the pinouts above and can't work out the the vid GND goes.
