Good evening, it's me again. I've been having issues with the Super Cassette Vision games on here.

https://forums.bannister.org/ubbthreads.php?ubb=showflat&Number=82767&page=1

I already thoroughly read through this thread from years ago and there are still a few things that aren't explained like this;

without that information from the softlist it won't be allocating / mapping the extra RAM, and no doubt the game needs it.


What is this code?

How do I implement it in the SCV.XML file?

Do I do it like this?

I'm genuinely confused about this, I have almost no experience with coding for MAME.

It literally shows you the two existing dataareas in the XML tree, yet you added yours somewhere at the end where it does not belong...

I apologize again because I'm new to this. I tried saving it like this and I still can't get the game to play past the course select screen.

The second dataarea in the current scv.xml is already defining the extra 4KB ram.
Quote

<part name="cart" interface="scv_cart">
<feature name="slot" value="rom128k_ram" />
<dataarea name="rom" size="131072">
<rom name="polepos2.bin" size="131072" crc="cb69903d" sha1="472900d7b7fa6cdf30014731dcc925ef5ca65499" offset="0" />
</dataarea>
<!-- 4KB RAM on cartridge -->
<dataarea name="ram" size="4096" />
</part>

So there's no need to add it then?"

How do I fix the rom then? Is it just not possible?

Define "fix the rom". polepos2 runs 100% fine in the SCV driver. Are you making a new dump or something?

my guess is they're trying to run without even using the Software List support, expecting it to auto-identify from a loose file.. because a lot of places still seem to say that the 'loose ROM' method is the correct way to use MAME, when it isn't

You need to select your course with the 1 through 4 numpad keys.. then hit "numpad + key" (EN in mapping menu).. then hit CTRL or ALT (which are the default 1+2 fire button mapping) and the game will start.
Those two fire buttons control acceleration + brake - using controls left/right turn, up/down choose gear. That's about it.

This is what happens every single time I get past the "track select", it simply crashes at this screen and I cannot get it fixed.

I've heard so many times about this so called "software list support" but how exactly do I use it? Everything I can find on Google gives you a vague understanding of what it is.

mame64 scv polepos2

that tells mame to launch with the 'scv' system and 'polepos2' from the software lists.

if you're not launching with the software lists it literally doesn't matter what's in the XML
