astrcorp.cpp: allow magibomb to boot (#7665)
* astrcorp.cpp: make magibomb to do something worth, WIP * Add vblank, DRY on memory maps * Split state machine, fix video, add default eeprom * m_draw_sprites -> m_sprite_dma * Add meat to astoneag * Confirm sprite drawing being same deal, no need for override * Move astoneage decryption data and ramdac declaration in a subclass, make screen always enabled for convenience
