@nic0344 @RetroJeff83 @RSDCDN @pr4m0d @illusionrip I also don't have any of the proprietary chips as well

@nic0344 @RetroJeff83 @RSDCDN @pr4m0d @illusionrip We spoke about it before. It's pretty bad, I hope @RSDCDN can get his system fixed up.

Everything is fried! The console was entrusted to me by Magno LA who could no longer take care of it — get well soon man. It originally belonged to Fred Christopher. #neogeo #aes #backfromdead Fault summary: following the use of an MVS adapter combined with a NeoSD Pro, the console fell into click-of-death shortly after… (basically a console feature indicating the 68000 is in a bad state — one or more main components is not responding as it should) The console wanted to take a vacation but this isn’t the time 😂 Diagnosis details below for the impatient ones 😝 😭 — here are the dead components: Z80 dead 68000 dead Neo-B1 dead LSPC2-A2 (unconfirmed) Work RAM dead (x2) Fast VRAM dead (x2) Diagnosis details: I started with a possible widespread short circuit — the cause can be multiple: incorrect power supply to the board, dead components, main crystal dead. Note: the LSPC2 had already been replaced. I first check the voltages across the main components (BIOS, CPU, YM2610…) and at the output of the power supply circuit — OK. I check all the clocks at the Neo-D0 output, responsible for dividing the 24MHz to feed the other chips — OK. I pull out the Briconeo: first impression, I’m having a lot of trouble running diagnostics on the 68k side (echo, etc.), I’m getting random bus responses on the 68k work RAM, palette RAM, VRAM and fast VRAM diagnostics… The Neo-C1 diagnostic responds well, the LSPC2 beta diagnostic too. I do have a click-of-death telling me something is wrong somewhere and that the console is rebooting trying to recover a good state 😭 However the reset doesn’t seem to respond… the bus might be too busy… So we’re thinking one or more little troublemakers are disturbing the 68000 bus… or several components that may have fried. I go back over the entire board under the microscope — it’s a long process… First step: check what has been modified or replaced. Remove the BIOS to fit a new socket, check for trace cuts, same for the LSPC2-A2. Probe all the TTL circuits (74x…) with the oscilloscope, the BIOS and everything that can interact with the 68k bus. I pull out the thermal camera — an essential tool sometimes… I have a hunch…: the Z80 is running very hot (40°C+), the 2K fast VRAM (40°C+) as well, and this is affecting the internal temperature of the LSPC2 on the right. Two new 2K fast VRAMs are fitted on sockets, and the Z80 is replaced and also socketed. Testing the Z80 in the tester — confirmed dead. Testing the 2K fast VRAMs in the tester — confirmed dead. The replacement is confirmed post-install by a more appropriate temperature reading. Smells like a short circuit that took out components in a chain 😭 While we’re at it, we replace the Neo-B1 too… and we get a more correct display: no more scrambled black image (which looked like a clock issue…) but a slightly pink click-of-death and a reset that works! That’s positive 🎉 We spend 2–4 hours sweeping the entire board on both sides: what’s causing this click-of-death? Given that everything looks fine trace-wise — double checked… We pull out the oscilloscope again and go through the 68k address and data bus — I have some inputs stuck at 0 regardless of reset or anything else… My gut says: let’s swap out this 68k. It’s fairly rare for this kind of component to fry, but there might be a corroded trace underneath — who knows… A new 68k is socketed and swapped in… We get a nice black screen! Well then 🙂 We put in the diagnostic BIOS and the M1 Z80 cartridge, and we get a diagnostic display with sound indicating the Z80 is working but that one of the 68k WRAMs is dead… (this is the 68k’s working RAM where the code lives, etc.) The lower work RAM is KO… we replace both… And we get a working console back 😅😅😅 This one came back from the dead 😀

@iFixRetro Beautiful work. 👍 What's the battery life like?

@BlueShell3D It's still available for sale!

@iFixRetro Sweet Jesus I want it

@bytesaber_ @PixelFXco It has motion adaptive or crt simulate that produces the same effect on it.

@iFixRetro @PixelFXco Any thoughts on how deinterlacing is handled? Is it good? I think being a 480i era system, this is a reality to embrace. But maybe it can be dealt with? I use Motion Adaptive with my RT4k, with mixed results.

@RageousX @jeffqchen I have a collection of obscure pc shit covered in dust

@iFixRetro @jeffqchen What the fuck dude 😂

I’m pretty much out of my mind buying this thing in a box🤪

The Morph 2K launches June 5th at 10AM Eastern for $199.99. We’ve spent the past few months refining the hardware, adding features, and getting units into the hands of testers and reviewers. We’re excited for everyone to finally get their hands on it. More launch details, pre-order info, features, and review timing below: pixelfx.co/post/morph2k-p…

@natalie_thenerd DVD video

Please look at my soldering iron's sleep screen. I'm obsessed

@Albasloth @PixelFXco It's pretty dang smooth.

@iFixRetro @PixelFXco How do you think these compare to playing on a pvm with component? Ive been on the fence if I wanna do an Hdmi mod on mine.

More gem install noods and system has been recapped.

@RobertDaleSmith @jeffqchen Right right. The hub is the main thing to get anything going

@iFixRetro @jeffqchen Controller only works with the hub. So need to write software/driver to talk to the hub to get anything flowing.

@RobertDaleSmith @jeffqchen Absolutely! You mean the hub or the controller? I can get it working with the older operating systems

@iFixRetro @jeffqchen I got one of these in recently. So sad the receiver isn't simple USB HID device. Some kind of custom USB vendor device that will take some poking and prodding to get working. If I make an adapter, will you open it?
