R-type conversion issues

[subcon959]

I've just about managed to get this done but have some graphical glitches that I'm not sure how to fix.

Anyone point me in the right direction? I've checked the soldering work but beyond that I'm not really sure where I should be specifically looking.

If this is Major Title to R-Type conversion with the extra RAM chip, then you've probably made a mistake in the track cuts or wiring. Can't really suggest anything specific other than to check it again or ask someone else to check it.

Thanks Paul, it is Major Title. I'll check over again more closely.

Ahh, I feel silly. I got mixed up between IC8(B) and IC8(T). All sorted now.

I'm relaunching this topic because I got a glitch gfx with my R-Type M82 conversion :

All the rest is working fine (gfx and sound)
I'd like to know if this glitch is present on other M82 conversions ? I want to understand who is responsible ? The conversion or my pcb ?
If someone can check ?

Not sure why you are looking to this old thread, it's about a completely different conversion that required hardware mods unlike mine which is pureply a rom swap.

I used the topic to avoid opening another one. I hadn't realised it was for an older conversion.
