Dr. Mario has only 32K of PRG (1x$8000) and 4x$2000 of CHR ROM.
No script seems to work correctly. The game uses MMC1 SEROM.

Any help?

In SEROM, CPU A14 bypasses the MMC4 and goes straight to PRG ROM A14, just as in NROM and CNROM. So for SEROM, you want the PRG part from NROM and the CHR part from the generic MMC1 script.

1. nrom.ad script does not work, gives an error. The nrom_gui.ad script works fine for the PRG ROM dumping.
2. The mmc1_skrom.ag gives only $2000 of CHR ROM. The mmc1_surom.ag assumes CHR RAM.
