Wolf Unit - Save fix (power cycle)
Beta; cabinet verified; timing passed at all corners. Seven original Wolf Unit games. Settings and high scores now survive a power cycle (they were restored corrupted on every power-on; a reset kept them). MK3 and UMK3 always start at the default volume after a power cycle, as the original games do; the other five keep it. Includes the page-flip fix for MK3/UMK3 Motaro/Kintaro/Shiva HUD and sprite flashing, and the DCS 16x output filter (hiss fix). Community hacks requiring separate ROM sources are not installed by this feed.

Now keeps high scores, operator adjustments (difficulty, lives, coinage, free play) and bookkeeping across power cycles; save with the OSD's Save NVRAM.

T Unit - ADPCM R7E announcer fix

Selection notes
T Unit ADPCM moved from the S12 baseline to the September 22 R7E announcer-fix build; the S20/S22 builds rejected on the cabinet stay excluded. T Unit DCS moved to the September 23 sound-fix build. These builds still have documented limitations.
V Unit - Cruis'n family r30
Beta; cabinet verified; timing passed at all corners. One core for Cruis'n USA, Cruis'n World and Off Road Challenge, the whole game in the FPGA at arcade speed. Full analog steering in Cruis'n World (map Test, then run Calibrate Controls once). New mappable Test, Service, Volume Up/Down and Nitro (Off Road) buttons, appended so saved button maps stay valid. OSD options for analog pedals on the right stick, pots on the DE10-Nano ADC header, and cabinet switches and steering motor via SNAC; with the defaults it plays the same as before. Includes the September 25 race-buzz and CPU timing fixes. The optional force-feedback wheel helper is not installed by this feed. Replaces the Cruis'n USA-only core; your Cruis'n USA saves are kept.

V Unit - War Gods r16
Beta; cabinet verified; timing passed at all corners. War Gods booting from its original hard disk, with full-speed DCS2 sound; fights run at about 98% of arcade speed. Fixes the power-on test error "U28 VR ASIC failed polygon draw test (V+ DMA ASIC Error E2)". Credits and master volume now survive a power cycle. New Volume Up / Volume Down buttons, appended so saved button maps stay valid. You supply the disk image: run chdman extracthd -i <War Gods CHD> -o wargods.img and put it in games/wargods/; the feed installs config/wargods.s0 once to mount it. OSD Audio Gain (default +12 dB) and Dither options.

Saves after MRA renames
Every game now ends in [blahm1d] (for example Smash T.V. (rev 8.00) [blahm1d]), so these games never collide with another collection's version of the same game. This is a one-time change.
MiSTer names a game's save (config/nvram/<name>.nvm) and DIP settings (config/dips/<name>.dip) after the game's entry name. To keep your high scores, settings and DIP switches, rename those files to the new name before first launching the renamed entry, e.g. Smash T.V. (rev 8.00).nvm to Smash T.V. (rev 8.00) [blahm1d].nvm. Older entries renamed earlier follow the same rule: RevX_09132026 became Revolution X [blahm1d], and Narc (rev 7.00) [v22 erase row] became Narc (rev 7.00) [blahm1d]. Your old files are never deleted by Update_All; factory defaults are installed under the new names only where you have none.
The newer Gladiator OSD and Legend of Kage CRT drafts have no corresponding binary; they are not represented as delivered features. Diagnostic Y Unit test-ROM and Wolf HUD-counter images are excluded. Wolf community-hack MRAs are excluded because their ROM sources are separate from the original MAME game sets.
All published MRAs retain the original game profiles and ROM load definitions. Only the core binding is namespaced; invalid double-hyphens inside XML comments are normalized where necessary.
Night Slashers - v1.4 sprite fade fix
Cabinet verified. v1.4 sprite/special-attack fade fix; DDR3 sprite graphics and audio updates. Custom MRA ROM layout preserved. Known issues: title-screen starfield animation and occasional sprite edge wrap.

Games: Japan Rev 1.2; Korea Rev 1.3; Over Sea Rev 1.2.
Core by blahm1d, built on JTFRAME by Jose Tejada (jotego), with Amber CPU contributions. Original credits and GPLv3 license are preserved in the source archive.
September 19 ROM-loading corrections
Ougon no Shiro now uses the Japanese ROM CRCs, the required text/graphics order, and all four MCU ROMs. Its 0x6D440-byte stream matches the published source memory map. It accepts ogonsiro.zip or the merged gladiatr.zip. NBA Maximum Hangtime also accepts merged nbahangt.zip. Both parent archives are indexed by the upstream ROM database. RBFs are unchanged; these metadata fixes have not been cabinet-tested.
Automatic ROM delivery still requires the upstream source registration and mirror sync: PR #8. A merged source change alone is not a verified download.
