Apps in this suite
TRS:80 — Technical Readout System:80
A compact reference + builder for ’Mechs and variants. Browse data, read TRO panels, and crunch G.A.T.O.R. quickly at the table or VTT.
- Large manifest of chassis/variants with stats, armor/internals, equipment, BV, role, and references.
- Tabbed readouts, weapons lists, and an integrated G.A.T.O.R. calculator with roller.
- Lance Builder with BV/tonnage/role tracking; export/import JSON for portability.
- Chassis catalogue with “owned” tracking and filters.
- Tech: pure HTML/CSS/JS; data sourced from MegaMek JSON (CC BY-NC-SA 4.0).
MSS:84 — Mobile Skirmish System
A portable hex-map + skirmish engine designed for quick play on tablet or desktop — no physical map or dice needed.
- Hex grid editor with terrain/height/cover, presets, undo/redo, PNG export.
- Tokens with names, pilots, team colors; turn/initiative tools and 2d6 roller.
- LOS rays, range measure, fire/visibility aids.
- Side-dock integration with Flechs Sheets for record-keeping.
- Optional online play: simple “Uplink” rooms using Firebase snapshots.
Cross-app workflow
Build your force once in TRS:80, then fight with it in MSS:84. Export a Lance from TRS:80 (JSON) and import it directly into MSS:84 — pilot details and team colors carry over.
