Hi Everyone,
I own a MVS-1C motherboard that has recently started reset looping on the "garbage green square block screen". However, it is only happening with Garou: Mark of the Wolves (Original Cart). I have tested this board on two different superguns with the same game that have sufficient PSUs and have ONLY experienced the issue on the MVS-1C. I will now list below all of my current tests and evaluations. This cart was previously working fine and has been played for over 80+ hours.
Motherboard Modifications: Stereo Audio Mod
Bios: Asian/S3 Ver.6
----------------------------
Supergun#1 and #2 - MVS-1C Motherboard
Other Carts Tested:
Result#1: Garou: Mark of the Wolves (Original Cart) - Cart reset looping on the "garbage green square block screen"
---------------------------------
Supergun #1 and #2 - MVS-1F Motherboard (Fully working motherboard, no unknown issues)
Other Carts Tested:
Result#2: WORKS and BOOTS FINE! Garou: Mark of the Wolves (Original Cart)
Would appreciate any input or suggestions regarding my MVS-1C and Garou resetting issue. Clearly the Garou cart is fine since it boots and play correctly on the MVS-1F. I don't understand why it would begin the reset loop? Normally this is due to low 5V and adjustments are suggested. It truly makes no sense.
I get it, that arcade hardware needs patience and I have patience and time to clean. But I feel like I have performed everything that I am aware and researched. I have read replacing RAM chips might help, however, I don't think I need to do this considering the MVS-1C "Working RAM Test" is fine (no errors). MVS-1F on both superguns performed correctly even with Garou.
ONLY the MVS-1C has a reset loop on the green garbage screen with Garou. I have double checked MVS-1C cartridge slot and pins look okay and are making contact correctly.
I do see an area under the cartridge slot solder side that may have some traces that are scratched. However, I have checked continuity and from the points of reference through the traces to the chip legs and these all checked out fine. I have plans to use a magnifying glass to TRIPLE check these traces.
So lastly, do older games use less processing power from the motherboards than newer games like Garou or KOF99/2000/2002?
Scratched traces left of A1 listed on board. I have tested these points. However, I may get positive on continuity if they all meet at ONE point then branch out to their respected chip legs.
Thanks,
