GRADIUS 2 ROM WONT WORK WITH NESTOPIA SOFTWARE

Is the board not starting up at all? Does it startup but fail a diagnostic check? Does it boot up and run, but have corrupted audio or video? If it does have corrupted video, is it background tiles, sprites, or overlay (fixed) text. Some boards won't boot up normally if a Test or Halt DIP Switch is enabled.Ģ) Identify the malfunctioning subsystem. Some boards need a DIP switch selected to enable Test Mode.

Some boards need a little more juice than 5.0V to run, but don't exceed 5.15V if you can help it. A decent entry-level EPROM programmer costs $200.Įventually, you'll also want soldering and desoldering tools - you'll need them to remove faulty components from the board to replace them.ĭecent entry-level soldering tools start at about $150.ġ) Make sure all DIP switches are set to OFF, and that the supply voltage is between 5.0V and 5.15V. I made a tutorial video on using a logic probe to test an EPROM here:Įventually, you'll want to have an EPROM programmer - it lets you dump ROMs, program new EPROMs, test logic chips, and test RAM chips. A decent starting logic probe can be obtained for around $20 from Amazon. You'll want to have a logic probe - it lets you see the logic activity for each line on each chip. A decent starting multimeter can be obtained for around $20 from Amazon. Use it to test for voltage levels on chips and for continuity on traces. I don't know what your current knowledge level of electronics troubleshooting is, so I'll try to explain things as thoroughly as I can without getting too far into the weeds.Īt a minimum, you'll want a digital multimeter. Here's the rundown on my process when troubleshooting a board.

I ended up writing a short essay, and we both agreed that the info may be useful for others so here it is: Chinese Chess (the title says Chinese Chese)ġ42.As part of troubleshooting his Gradius II PCB, asked me through PM for a summary of my diagnostic procedure when looking at a board.

Because there's 150 games, this is pretty long. Here's a picture of the menu (it looks pretty nice IMO, better than just text on a black background)Īnd here's a game list (the seller on Aliexpress has one, but it's truncated and inaccurate).

I know that it looks like the game's running on an emulator on my computer, but the multicart's undumped AFAIK, and it's just my NES connected to my monitor's composite input. It's also a pretty new multicart, as the title's dated March 3rd, 2015.

The multicart claims to be made by a company called 'Shenzhen Spritemind Software Co.,Ltd.', who I can't find any mention of anywhere on the Internet. I took a few screenshots, and have written up a game list. Just search '72 pin 150 in 1' or something) for $25, because I was annoyed with people on eBay price gouging NES games. I just got a pretty good NES multicart off of Aliexpress (I don't want to be accused of advertising or something, so I won't post a link.
