v1.1
3566ba2

Adds Magical Error wo Sagase (Technosoft/Jaleco, 1994), the second and only other game on the dual-68000 + Imagetek I4220 architecture. Same verified VDP, CRTC display window and renderer as Hyper Duel v1.0.

What's new

  • Magical Error wo Sagase: separate RBF (Magerror_20260719.rbf) and MRA
  • IKAOPLL (cycle-accurate YM2413 by Sehyeon Kim) replaces the YM2151 for this title
  • Shared RAM moved to SDRAM to fit the larger 128KB region the game uses
  • System glue parameterised: one RTL tree, GAME_MAGERROR selects the build

Install

Same as v1.0. The downloader db now includes both games automatically. If installing manually, Magical Error needs its own RBF (magerror.rbf in _Arcade/cores/) and the magerror.zip ROM set in games/mame/.

Hyper Duel

The Hyper Duel RBF is unchanged from v1.0 (Hyprduel_20260719.rbf, md5 87b6ee7d). No need to re-download if you already have it.

Verification

Both the magerror SDRAM soak (2200 frames, all integrity counters zero) and the Quartus timing analysis (setup slack +0.285 ns) passed before deploy. On-hardware attract mode confirmed matching MAME.
