Metal Slug X Protection Issue

Hello!

My apologies if this has been covered. I went through every thread and didn't find any info, nor anything searching.

I'm using the .neo files from my NeoSD where every game functioned fine on my two MV1C boards. When loading Metal Slug X, I get the red screen of text warning about running on official Neo Geo hardware. Good 'ol MSX and it's protection chip. Whomp whomp :D

Is there a work-around for this, or is it just the odd game that's not supported (yet) due to the unique protection? Thanks in advance for anyone that reads this!

Relevant info:
Mode: MVS
Bios: Unibios 4.0
I've tried setting to AES mode in the Unibios, but same error.

Ended up figuring this out. Posting it here in the hopes it saves the next person some time.

- Source a Darksoft ROM set (google is your friend)
- Use this tool: https://gitlab.com/loic.petit/darksoft-to-neosd/
- Now protected games will work perfectly, and you still get the advantage of the .neo format
- Play Neo Geo as nature intended 8-)

Hi, thanks for posting your solution. I used the Darksoft-to-NeoSD tool to convert the Darksoft romset to NeoSD format, but Metal Slug X is still throwing the same error. Am I missing a step?
