are they HiROM or LoROM? How much SRAM do they have, if any? could you ran MESS with -logerror and post error.log?

and which address are they trying to access when they dies (in other words, which address should be mapped differently)?

I'm currently unable to test SNES directly...

They are BS-X slotted cartridges. You can look in xml.cpp in byuu's snesreader to find out the mapping. The mapper type for those two games is BSCLoROM.

then it's expected that they do not work... we don't support yet neither BS-X nor Sufami Turbo games!

I should add them at the top of the bug page...

thanks for pointing it out smile

I don't think you need to support the BS-X BIOS stuff. You just have to map the ROM in the banks $80-$bf differently.
Relevant part of xml.cpp:
Code:
    xml << "  <rom>\n";
    xml << "    <map mode='linear' address='00-1f:8000-ffff' offset='000000'/>\n";
    xml << "    <map mode='linear' address='20-3f:8000-ffff' offset='100000'/>\n";
    xml << "    <map mode='linear' address='80-9f:8000-ffff' offset='200000'/>\n";
    xml << "    <map mode='linear' address='a0-bf:8000-ffff' offset='100000'/>\n";
    xml << "  </rom>\n";
    xml << "  <ram size='" << strhex(ram_size) << "'>\n";
    xml << "    <map mode='linear' address='70-7f:0000-7fff'/>\n";
    xml << "    <map mode='linear' address='f0-ff:0000-7fff'/>\n";
    xml << "  </ram>\n";
    xml << "  <bsx>\n";
    xml << "    <slot>\n";
    xml << "      <map mode='linear' address='c0-ef:0000-ffff'/>\n";
    xml << "    </slot>\n";
    xml << "  </bsx>\n";

ok, but the support for the BS slot would still be missing. that's why I never bothered about the proper mapping.

I know very well how bsnes maps them wink

Bug report!

Star Fox (USA) has had a regression. Graphics appear to be split into 4 bands. 2 bands show correct graphics and 2 are garbled. Tested with the latest SVN.

Pro Kishi Jinsei Simulation - Shougi no Hanamichi
<- this jumps at 0xc00000 and there's currently nothing mapped there, incorrect cart mode?

running it with -log reports in error.log that the game uses SA-1

given that all the lists of special chip games have different translations for Japanese games, it's probably a special chip game that was missing in the Wiki list...

EDIT: this should be more reliable than Wikipedia:

http://snesemu.black-ship.net/misc/hardware/-from%20nsrt.edgeemu.com-chipinfo.htm

could someone fix the lists in our SNES bugs page?
