Easy to fix, if you can write a 27c800 you can also dump your v4 and check the integrity. 065-v1.v1 1.00 MiB 1,048,576 CRC: ce8b3698 SHA1: 7d75e2a5cf8c90be422f8b425447e81597fe145a 065-v2.v2 1.00 MiB 1,048,576 CRC: 659f9b96 SHA1: 62f40365212153bc3b92a1187fa44f6cdc7f7b83 065-v3.v3 1.00...

I worked a lot on the labels with Photoshop to recreate them like the originals ! Even the japan one ! the irritating maze !

let's wait for them to replace as many parts as possible with new components, if I found a kit I would buy it immediately :-)

i love you all guys.... but i need a tutorial for dummys with step by step, so many part ! :unsure:

And what about the repro cart ? Any seller for the empty cart ? or a kit to assemble and flash later ? :-)

Maybe i need a long explanation because i still not understand how to interpret this value on eeprom. Check here, we have more wird allocation; <dataarea name="sprites" size="0x1c00000"> <rom loadflag="load16_byte" name="059-c1.c1" offset="0x000000" size="0x200000"...

No man, I’m not sure about what chip is used but 100% that are all new stuff. This type of project already exist for snes and other. Let wait for detail.

Crazy stuff around the web. "I am so close with the NeoGeo AES 3.5 Board. No Errors on the PCB now, few warnings, need to sort the silk screen, and missing a gnd pad hole in the corners." The creator of this project say that he will publish on github. Source: https://twitter.com/chris_jh

Man, what you think about start from the base with cleaning ping with glass fiber pen ? there seems to be a nice layer to scratch off..

Hello to all guys ^^ I'm trying to do a conversion of ViewPoint from a copy of Super Side Kik 2 (poor soccer game, no one love it) All working fine, program will start so i can see P1 is good, sound also is good but someting wrong here with C roms. View: https://youtu.be/TvlqWHcUW7M I know...

Im trying to get a conversion of MagicianLord from GoalGoalGoal PROG BK1 and CHA 256, why ? Because a get it for 10 Euro and Magician lord is to expensive for my pocket ^^ This is rom setup: C1 from joined 1-3-5 C2 from joined 2-4-6 And graphics work fine For the audio the original rom is...

I would also like to express my sincere gratitude for all the information on the neogeo theme that I have been able to read and learn. twistedsymphony & Fluffy thank you for all the information shared over the years, it has been of great help and interest to me.

I converted last resort on proggsc for my collection and i noticed that the audio was audible but some sound was not correct so i understood that no game used the 8mbit mask rom as first v rom. I solved by adding all the v roms into one 27c160, now the audio is heard correctly. Thanks for all...

Yes, every game that uses a gsc prog uses 16mbit vroms but is it possible to set the jumpers so that I can use 2*8mbit eproms? From what I've read it seems not Only SpinMaster uses an 8mbit vrom but because it only occupies the v1 https://www.mvs-scans.com/index.php/Spin_Master

Hello guys, From what I understood by reading all the documentation that I could find around I seem to have understood that it is not possible to set the jumpers to use 8mbit v roms but these must always be 16mbit. did I get it right ?
